JVI or EVI

My experience with EVI (electronic viewfinder) consists in communicating with Sony a7, a7 II, a7R, a9 cameras, some mirrorless Panasonic, Olympus and Fujifilm. For a long time I shot on SLR cameras with OVI (optical viewfinder), and after them it was very inconvenient for me to use EVI, but over time I felt all its charms and radically changed my mind.

The internal structure of the camera

The internal structure of the camera

On the Internet, I often see phrases like "Once I tried EVI, I realized that this is not mine." Such words can be said about me, but, fortunately, life made me communicate with EVI more closely and come to different conclusions.

Please note that OVIs are of two types - for SLR cameras and for rangefinder (mirrorless) cameras. The JVI design for these two different types of cameras is fundamentally different. In this article, by OVI, I mean a viewfinder specifically for SLR cameras.

EVI, power consumption and inclusion

One of the most serious drawbacks of EVI is considered volatility. In order to see what you want to shoot, in the case of EVI, the camera must be turned on. In this case, the matrix of the camera will be turned on, the processor and the EVI sensor will work. All this consumes energy, and even worse, it takes time to turn on the sensor, processor, and other hardware. As a result, there is a huge lag between turning on the camera and displaying the image.

Electricity consumption can be cured with more capacious batteries, or spare batteries - it's not a big problem for me... But the EVI lags when turning on, turning off, exiting the camera from sleep mode, activating the sensor after it was turned off while viewing the footage, and so on, get on your nerves. Lag when turning on EVI - biggest flawwhich I highlight in EVI.

This drawback can be easily solved - for example, always keep the sensors on, or just make the lags very short. I believe that in the future there will be no problems with power consumption and lags when turning on / switching a camera equipped with EVI.

Is the finished result really visible in EVI?

A strong advantage of EVI is the ability to see the finished result before releasing the shutter. But there are reservations. The observed image is formed by a sufficiently small sensor of 1-2 Megapixels, which does not transmit the entire amount of data received from the camera’s matrix. In this case, the JVI is more informative, the matte screen of which, in fact, has a very large resolution. Also, the camera processor is not able to immediately apply all the enhancements for the image, such as control of dynamic range, color, noise reduction, distortion and vignetting. As a result, the image after the shutter is released may still be slightly different from the one I see in EVI.

The Sony a7 camera is very noticeable that the image is still being finalized after the shutter is released. It often happens that after the shutter is released, the camera shows the shot, it takes 1-2 seconds and the picture changes its appearance - it undergoes additional processing, which could not be obtained immediately.

I really like that when working with EVI, a finished picture (obtained after releasing the shutter) can be viewed immediately without taking your eyes off the camera’s eye. In the case of the JVI, you need to take the camera away from your eyes and look at the main display to see the received image. It turns out that with EVI much less time is spent on monitoring the shot material.

As for the small differences from the image observed in the EVI and the final frame (after releasing the shutter), this is just a processor limitation, which can be easily cured in the future. Yes, and many cameras already fully display in EVI directly the frame that will be after the shutter is released - with all additional image quality adjustments turned on.

EVI in the studio

Usually, sighting through an EVI makes it possible to observe the picture that will be at the time of shooting, but this may not always be convenient, and sometimes it is contraindicated. This primarily concerns shooting in the studio using pulsed light. The bottom line is that in the studio all frames are usually shot with manual settings exposure. For example, in the studio it is most often used exposure control mode "M". Suppose I set ISO 100, F / 4.0 and 1/125 sec. With these settings, the camera’s EVI will display a black rectangle, since there can be very little pilot light (pulsed flashes will be used at the time of shooting). It is practically impossible to focus on and compose the frame in such conditions. To overcome this inconvenience, on cameras with EVI there is a function that disables “displaying pictures with actual parameters” and includes “display simulation”. In simulation mode, the camera does not use user-defined parameters. exposure, but selects its optimal ones, in which the EVI produces a distinct image, through which you can focus on sharpness and compose the frame. If you turn on the simulation, then in this case it will be very convenient to endorse in the studio.

In the Sony a7 camera menu, the function that is responsible for the display mode is called 'Display. Live View '(Setting whether to display settings such as correction exposure, on the display screen). This function can take only two values ​​“Display. Param. ON ”and“ Display Param. Off. "

When I first got into a studio with a mirrorless camera using EVI, I did not know about the possibility of simulation and it was very difficult for me to shoot.

Of course, simulation of the display can be useful for other types of shooting, for example, for shooting with very slow shutter speeds.

Inertia EVI

EVI suffers from inertia - when rearranging a frame, the display of changes may occur with a delay, and the EVI may slowly rebuild with a strong change exposure filmed scene. For example, if I was shooting in the shade of trees, and sharply pointing the camera towards a bright street, then in EVI instead of the expected type of street, for an instant I will get a white spot that has normalized and will take the expected form over time.

With a sharp change in lighting, the Sony a7 loses consciousness and within a few seconds adjusts to the correct exposure.

Most likely, this drawback can be eliminated and in the future cameras with EVI will be deprived of this drawback.

Pixelization

They say that one of the main problems of EVI is the pixelation of the image. Perhaps this was a problem many years ago when sensors for displaying images in EVI had low resolution. With the cameras that I indicated at the beginning of the article, I did not observe or did not notice the pixels of the EVI display.

If some EVIs have such a disadvantage, then over time the number of pixels on the EVI sensors will increase and everyone will forget about this problem.

Feeling of light

The EVI sensor has a constant or variable brightness within certain limits. On the one hand, this is a great achievement compared to the JVI. In the JVI, the brightness directly depends on the maximum aperture of the lens and the illumination of the scene. But constant brightness can play a trick on the eyes of the photographer. When shooting in bright light, I often saw that when I was vising through the EVI, my eye was tuned to a certain light intensity, and as soon as I took the camera away from my face and looked at what was happening without EVI, it took my eyes time to change to another illumination. The same thing happens when in the bright sun you bring the camera to your face, while in EVI you can’t see anything for a while until your eyes accommodate.

I think that this drawback of EVI can be solved with brighter sensors, as well as light sensors (similar to those that are in modern smartphones and automatically adjust the brightness of the display depending on the light).

Viewfinder linked to focus system

Speaking about EVI and OVI, you need to immediately understand that the technology for displaying the future frame is directly related to the focusing system. Very fast and fairly accurate phase focusing systems based on separate sensors have been developed for the OVI. For EVI, phase or other focusing sensors should be placed directly on the camera’s matrix (SLT cameras do not count, since there is a mirror). So far, there is an opinion that focusing on mirrorless cameras with EVI is noticeably worse than on SLR cameras with AVI. But in fact, mirrorless cameras with EVI only need to pull up and refine their focus system a little, and some cameras with EVI focus already very, very well. Separately, there are SLT cameras, which also use EVI, but at the same time they have a fixed mirror and phase focusing modules, which are characteristic of cameras with AWI.

Conclusions on EVI and JVI

Advantages of JVI

  • JVI non-volatile, works even when the camera is turned off. True, modern OVI in some cameras have their own limitations, which are primarily associated with a transparent LCD display for displaying auxiliary information. I have considered this issue in detail here.
  • Lack of inertia, instant sight of the scene. Very important for reportage photography.
  • High matte screen resolution with the possibility of replacing it.
  • The brightness of the JVI automatically changes depending on the scene being shot.
  • Subjectively, many users like the non-digitized image from the JVI more than the digital image when sighted through the EVI.

Disadvantages of JVI

  • The high cost of production and design complexity. For JVI, you need a very large number of mechanisms that can fail (tested more than once on personal experience). First of all, JVI needs expensive glass pentaprisms, mechanics of mirror control (two mirrors), separate metering sensor and separate focus sensor. When the cost of production is reduced, for example, when replacing a pentaprism with a pentamirror, the display quality decreases.
  • For accurate and perfect focusing, the mechanisms of the mirror / second mirror and the focusing module need to be very precisely calibrated; it is sometimes extremely difficult or impossible to programmatically make accurate focusing with each lens.
  • Simple ARIs have 90-98% of the frame coverage, the remaining percentages at the edges of the image are not visible. In expensive models, the percentage of frame coverage reaches 100%, but the cost of creating such a JVI increases. Details therefore you will find here.
  • Noise at work. Part of the shutter noise It is created directly by the movement of mirrors and their control mechanisms.
  • The movement of the mirror creates excess stirringthat may affect image blur. Some cameras have a tangible Mirror Shock.
  • Focus area limited by focus points due to reduced additional mirrorresponsible for focusing.
  • Image distortion. First of all, the JVI incorrectly displays the appearance of the blur zone, the bokeh when viewed through the JVI is not displayed at all what it will look like after the shutter is released. Also, when working in backlight, the final shot may have light artifacts (reflections, glare, etc.) which are not visible in the JVI.
  • The opaque OVI screen, mirror and matrix may become dirty, which reduces comfort during shooting. In EVI, only the matrix is ​​contaminated.
  • You cannot shoot video through the JVI. On cameras equipped with an OVI, the main display with the Live View function should be used for video recording.
  • JVI has a certain dimming timewhen the mirror is in a raised state. In this position, focusing and metering also stop. exposure. In some cameras with EVI it is possible to constantly sight, even when shooting in a series, and focusing can work constantly, but for this you need to use an additional electronic shutter (not all cameras with EVI have an electronic shutter).
  • JVI may suffer from flarethat affect metering exposure and / or illuminate the image for long exposures (this disadvantage is treated with a special eyepiece shutter, I examined this issue in more detail here) But EVI is completely devoid of flare.
  • JVI requires use retrofocus wide-angle lenses (due to the presence of a mirror, the working length is lengthened).
  • OVI does not allow you to visually stabilize the picture when using the image stabilizer built into the camera. To stabilize the image in the JVI, you need to use lenses with a stabilizer
  • JVI sometimes does vacuum cleaner effectwhich can be unnerving.

Advantages of EVI

  • When sighting EVI immediately displays that imagethat will be obtained after the shutter is released (with some reservations described in this article). Also, in the EVI it is convenient to see the real-time image settings and select the best option.
  • The conclusion is very ba lot of supporting information. First of all, it helps to use a number of very useful functions, for example: focus picking, live bar chart, function - "zebra", electronic level and many others. Also, EVI allows you to instantly increase the selected part of the frame in real time, which can be very useful for accurate focusing.
  • EVI allows you to view the photo you just received without taking your eyes off the eyepiece. Allows you to more quickly control the quality of the filmed material.
  • The focusing method used with EVI is less prone to problems with back / front focus.
  • Allows you to dig into all the settings of the camera without taking your eyes off the eyepiece EVI. In the case of the JVI, to access all the settings, you should remove the camera from the eye and turn on the main display.
  • Constant, or automatically adjusted brightness at any aperture value, excerpts and the scene being shot. EVI brightness does not fall when closing the iris, for example, to view the depth of field.
  • Simplicity of construction (unlike the OVI, it does not require mechanical mirrors, a matte display, a pentaprism, an additional focus sensor, an additional metering sensor exposure and heaps of serving devices). Also, this design allows you to make cameras more compact and lightweight.
  • EVI works silently (unlike clapping mirrors), and also does not create unnecessary movement from the movement of the mirror.
  • EVI has a greater potential to expand the area of ​​the frame responsible for focusing. Theoretically, the entire area of ​​the frame may be responsible (or already responsible in the case of focusing by contrast) for focusing.
  • Large (in fact 100%) percentage of frame coverage. In the JVI, it is not so easy to achieve 100% frame coverage.
  • The ability to simultaneously sight through the EVI and connect in parallel other devices for image output. For example, you can connect a monitor to the camera with EVI, through which other participants in the shooting will see what the photographer is taking, without disturbing him at all.
  • From the previous it emerges that EVI allows you to shoot video.
  • EVI allows you to visually stabilize the picture when using the image stabilizer built into the camera
  • Shutter release time may not be available when using the electronic shutter.
  • Missing Mirror Shock

Disadvantages EVI

  • Inadequate brightness. On a sunny day, it constantly seems that the image in the EVI is too dark (in the future, the flaw can be corrected)
  • Low resolution of the sensor, forming images for display in EVI. Here you can add low-quality sensors, which when sighted create various unpleasant visual artifacts (in the future, these shortcomings can be corrected)
  • Volatility (theoretically it cannot be fixed, but in the future it can be improved by using sensors with lower power consumption and more capacious batteries, not everything is so bad now)
  • Inertia, lag in image output (in the future may be fixed)
  • Power-on lags or at low temperatures (may be fixed in the future)
  • Matrix heatingoverheating of the matrix, which in the first place can be negatively displayed at the noise level (in the future it can be fixed)
  • Difficulty working in low lightrelated to the brakes of image display and / or displaying an image that is too dark (may be fixed in the future)
  • In EVI artifacts from a dirty matrix are much more noticeable, this reduces comfort during shooting (in the future it can be fixed with an improved matrix cleaning system)

Some of these deficiencies have been corrected to one degree or another or are actively being corrected.

I can summarize that EVI technology has a lot to develop, its shortcomings can eventually be improved by the best hardware and software solutions. OVI technology has reached its logical end and does not have serious opportunities for improvement. At best, the JVI will move toward a hybrid JVI. Nevertheless, you need to understand that the JVI is a very ancient, proven technology that will please more than one generation of photographers.

  • Vladimir

    Thank you for the article! Curious and informative, worth considering. However, the question is - how about the speed of EVI versus OVI? Those. What are the extremely fast shutter speeds that cameras with EVF can shoot?

    • Arkady Shapoval

      The shutter speed is set by the shutter speed, this does not apply to the method of sight. Therefore - at the same exposure.

      • Vladimir

        Those. and there is no dependence at all?

        • Arkady Shapoval

          In fact - none.

  • Basil

    Arkady, ovi will be JVI only on older carcasses. For example, in ov d40 horseradish what you see Recently, I used d810 and realized what a real JVI is. So if you consider ovs on younger carcasses, it is not known what is better than ovis or evi. In the case of d810, I do not know what could be better than his JVI.

    • Arkady Shapoval

      Ovi canon 1dx could be better.

      • Basil

        Is this the one that directly competes with d4s?

        • Arkady Shapoval

          Yes, he has a larger increase (i.e. he is larger)

          • Basil

            Cool . But there is no way to verify this. No owner in his life will give such a d4s class car for review :(

            • Arkady Shapoval

              Representatives can give them, and it’s easy to find out from the physical data from the instructions :)

      • Denis

        Arkady, how can I explain that in my Nikon f100 there is an JVI with an increase of 0,76 (the same as on the Canon 1Dx), and on the Nikon D4s, D4, D810, Df there is already an increase of 0,7? By the way, the difference in magnification is small, but it is even felt during sighting)

    • Alexey

      canon 6D and canon 5DM3 have a lighter, significantly lighter JVI than the D800 and D810.

      • Yarkiy

        Yeah, much much much better.

        • Alexey

          and much more significant)))
          it's hard to say how Nikon manages to make such a dark JVI.
          and even in 6D, you can change the focusing screen in 2 minutes to work with manual lenses))) and put on the carcass old manual lenses including Nikon lenses)))
          not to mention the fact that the shutter sound 6D in quiet mode is almost inaudible.
          however, this is not available to the owners of Nikon - neither a quiet mode nor a clear light OVI)))
          they can only troll in the comments)))

    • d.martyn

      The best JVI through which it looked was Kiev 88 (medium format), D4C nervously smokes.

  • Andrey Kondratenko

    "When production becomes cheaper, for example, when replacing a pentamirror with a pentaprism, the display quality drops." Arkady, if I'm not confusing anything, a pentamirror is just the lot of cheap DSLRs. In any case, top cameras are equipped with pentaprism. And the main problems are the inertia and difficulty of working in poor lighting. Power consumption is easy to resolve with additional rechargeable batteries. The rest of the problems are practically solved. On my own I will add that different EVIs display the picture in different ways. Recently, when I tested the Olympus OM-D EM5 II, I came across the fact that the TFT-EVF is very cold in the picture. Therefore, I regularly checked the BB.

    • Arkady Shapoval

      Fixed

  • Anatoly

    The article is almost empty ...
    To consider such obvious things - OVI (a rudimentary grandfather with a century of history) versus a modern and fully functional EVI ..
    There are already obvious things, which are stupid to talk about - how can one generally oppose JVI against EVI ...
    Wait for the next article - which is better abacus or calculator?

    • Arkady Shapoval

      What non-trivial things about evi and ovi additionally need to be included in the article?

      • Anatoly

        You don't need to turn on anything else ...
        It's just that the topic itself is empty ...
        To compare the practically obsolete rudiment (OVI) and modern EVI with normal modern quality ...

        Have you ever seen comparisons and tests, for example, VAZ-2101 and LandCruiser-200?
        It is foolish to compare what has become obsolete and is no longer modern with what is modern ...
        These are different things - it makes no sense to compare ..
        Compare then, for example, the gross product of Germany in the 21st century and the gross product of Germany in the 14th century ... This is a natural trend ..

        PS
        The article is immaculately good and written as always excellent - but the topic for the article itself is chosen - a comparison of the obvious ... alas ..

        • Arkady Shapoval

          Ovi has not yet outlived, you perfectly understand this, but those users who want to change OVI to Evi will be able to quickly understand what they are losing and gaining. In the previous commentary you wrote about the inferiority of the article, now you just moved out :) The cost of "Zhiguli" like Canon 1dx is many times higher than budget land cruisers with Evi, and we perfectly understand the ratio of serious photographers who drive Ovi and Evi.

          • Anatoly

            Damage is not articles but topics.

            • Arkady Shapoval

              Okay :) maybe someone from the commenters will add something else exclusive on evi or ovi

              • AM

                The direct disadvantages of JVI, in comparison with EVI, include the dimensions and weight when using a pentaprism. The indirect disadvantages of the OVI and the indirect advantages of the EVI include the high integration of modern matrices - the AF phase sensors and the exposure meter are located on the matrix. Part of the disadvantages of the JVI in the complex can be attributed to the tendency to back-, front-focus on the CZK. You can add about the volatility of EVF - it is impossible to sight with the camera turned off.

  • anonym

    Thank you for the article! Informative, interesting, but for me personally EVI is unattractive, let them finish it further, and then we'll see.

  • Anonymous 1

    Twenty five again! A man shares with his readers his thoughts, feelings, that which seems interesting to him. Well, if you don’t want to read it, don’t read it, open the porn and enjoy the depth of knowledge! What do you strive to keep Arkady, wise guys ???

  • anonym

    Anatoly, it seems, is a supporter of the new for the sake of novelty: everything that is not the most modern old-fashioned means into his trash heap, atu-atu ...

    • Anatoly

      no.
      We leave everything that is better, and everything that is worse goes to the trash.
      Everything that replaces something that was developed taking into account the shortcomings of the previous something and is a new generation of something - is definitely better than what is worse and what is yesterday.

  • Yarkiy

    And I don’t like EVI since the time of cassette-film video cameras, (although this is not quite the bottom and the same). And I also used modern EVI, although not much, so I bought a DSLR, JVI is great! I don’t know what is going to happen, so that I voluntarily abandon the JVI in favor of the EVI.

    • jurij

      Then (in the future it will be fixed) we will buy.

    • Jury

      I don't like them either. Even when I used the Panasonic Lumix DMC-FZ7, I tried to switch to electronic OVI - a perversion when the image from a small LCD screen is in the eye of the optical viewfinder.

    • Ruslan

      This is a matter of habit.

    an excellent article, once again consolidated the previously formed opinion. A comparison like a Lada with a cruiser is a real nonsense. We all know who marketers are and that they are not at all interested in any solutions to exist forever. After all, honestly tell me that to watch just a good movie, it is not necessary to have a 4K or 8K screen resolution, so for sure with a photo ...

  • varezhkin

    some kind of excuse for EVI came out ... “In the future”, “will be improved”, “there will be no problems” - this is practically written after each paragraph. There is nothing better than a good OVI with a magnification of at least 0.7x or like the fm3a 0.83x.

  • Andrei

    For example, EVI is convenient to use from a tripod for macro or subject. But still, JVI is always preferable in most situations. Thanks to Arkady for the article.

  • Peter Sh.

    It turns out EVI - the same LSD display, only small and for one eye.

    I do not like. I tried it, I didn’t like it at all. I prefer to look at the world through optics, rather than electronics.

  • R'RёS,R ° F "RёR№

    “Ovi will be OVI only on older carcasses” - this item should be the first in the list of shortcomings of OVI, it is he who is most surprised by the owners of “crops” who have looked into my EVI by no means new and not expensive mirrorless.

  • anonym

    For a long time I shot with a video camera. When shooting, there was a feeling of detachment from what was happening. Maybe that's why I opened my other eye ... And when you shoot with a DSLR, you still feel close to the subject! And the magic of classic photography lasts for a while!

    For video, EVF is better: it is more convenient to shoot than on the LCD screen. And for a photo - it is more pleasant and better than JVI! At least for now…

    PS. Old analog technologies are slowly dying out. You can't get away from this ... New - for young people. She often does not see the difference ...

  • Sergei

    And how does EVI behave at low, near zero and lower temperatures?

  • Pastor

    To be honest, I never understood much sadness about the size of the JVI. I can simultaneously shoot on the initial carcass with a small JVI and advanced with a large one. Yes, the difference is visible, but it doesn’t bother me at all (maybe my eyesight is good, or maybe it’s picky in this regard). In principle, I don’t care, I focus on 500d or 7d, on d7000 or d3300. It is quite comfortable both there and there. EVI tried and noticed the pros. But I love high-speed shooting, and a number of limitations of EVI do not yet allow it to fully enjoy. That is why in 1dh and d4s there is still an OVI, and in many other professional cameras. I am glad that the article pays much attention to the future. When the technological problems are resolved, I will be happy to switch to evi, though, I suppose, the manufacturers will decide for me. As soon as the quality and convenience of the EVI exceeds the quality and convenience of the JVI, they will immediately appear on all Nikon and Canon cannons. Hopefully over time the EVI will still be prompting how to choose a better angle and which focal length with aperture to use to get a masterpiece :)

    • Kotofalk

      “As soon as the quality and convenience of the EVI exceeds the quality and convenience of the JVI” - it still started, for example, to finish the still small vidoshukach o-md e-m5 (larger in the e-m5ii) in size yak in 1d mk2 and larger for 60d, and in 650d wonder why it's important. This update of the picture in 120 fps is practically not necessary to navigate on the reports, but from the ability to immediately bachiti the picture and make corrections with the wheel online is very useful, for at night focus on there, de no ovsh, no good fun)

      • Pastor

        Unfortunately, I did not see this device. So I can’t say anything essentially. If not in essence, then, as I said above, it’s easy for me to look into any viewfinder of any DSLR, at least the initial crop, at least ff. But in general, if EVI is so good, then I want to hope that we will see it in new mirrors. I think it is unlikely that Nikon and Canon are so slow-witted that they miss the fact that EVI has surpassed JVI.

        • Ruslan

          Why are you writing something wrong ... EVI in DSLRs? EVI just replaces the mirror.

          • anonym

            A DSLR is not a mirror ... A DSLR is a Big Black Cool Camera ... Unfortunately for many ... Well, not for everyone!

              Not necessarily cool and black, it can be pretty and red.

    • Dim

      I will support the account of the JVI in ff and crop. There is a difference, but it cannot be said that it is fundamental. I calmly move from D40 to D700 and to D300. And it’s interesting for others to shoot

  • Alexander

    For my sony a37, I would add a couple more virtues evi for people wearing glasses.
    The first is the bulging eye of the viewfinder (in other cameras it is annoying that glasses are constantly imprinted in the face when you reach for the eyepiece).
    The second is a large diopter adjustment (I have it at the maximum, but for the younger nikons and canons this setting is not enough for me, it's hard to see)

    • Alexander

      Solve the problem with contact lenses. I have been wearing it for 13 years - it is very comfortable and a more gentle option for vision.

          The lenses are now very pretty. Consider what's in them, what without them. And everything is in order with the vessels, as far as possible with my eyesight. I have a serious disadvantage and I cannot wear glasses (because of the optical power, everything floats before my eyes in glasses). Lenses - OK, no problems at all. Although I can't see well even in lenses, the diopter adjustment of the d7000 saves. =) But bokeh without contact lenses is such that many lenses would sigh with envy ... =))

          • BB

            yeah, and the stars are huge))

            I myself have been wearing lenses for more than ten years, I take 0,5 less than needed, and my vision does not fall, unlike glasses - for five years of wearing a diopter for a village.

            The only thing is that during long-term shooting (5-8k frames) the lens starts to dry out, you need additional. humidification, especially with 'vacuum cleaners'.

            • Alexander

              You might want to experiment with the type of lenses. It is worth trying those with the highest air transmittance and water content. I wear maxima (not expensive, but so-so), but Cooper Vizion is much better, albeit twice as expensive. By the way, without using moisturizing agents, they have the other side of the coin - the eye gets used to moisturizing and stops producing a tear itself in the right amount, and many drugs from these series constrict the vessels in the eye, which in my case is absolutely impossible. But on the whole, lenses are an INDISPENSABLE THING. I myself am satisfied and happy))))

              • BB

                Yes, I used to use B&L, quarterly, recently switched to others (I don't remember the name), also quarterly, and before that I tried different ones.
                Drying happens precisely with prolonged continuous shooting (sports dances), and I don't use moisturizers, everything is ok. By the way, flushing liquid can be used as a 'budgetary' humidification. drops have a short shelf life after opening.

  • Igor

    EVI cannot yet be a replacement for JVI. And another 10 years will pass until it begins to displace optics from the DSLRs.

    Sometimes the novelty of technology and technological progress do not bring convenience. So it was with Sonya's translucent mirror. It’s the same in other areas. For example, the electronic gas pedal in a car infuriates me! And they are shoved into all modern cars ... In addition, they shove absolutely unnecessary auxiliary electronic systems into the car, which are absolutely useless.

    • Ruslan

      It's a bullshit. Many photographers have already switched, or are going to switch to mirrorless mirrors. And do not compare the camera with the car. the camera is already completely electronic, why are there extra analog elements there. It's all exactly what to put analog devices in an electric car such as Tesla.

      • Peter Sh.

        I have not yet seen a single professional with a mirrorless mirror. In two weeks I’ll shoot international competitions, I’ll specially check it.

        • grandfather Fedor

          Unsubscribe, or give a link

        • Ruslan

          Yes, even though Arkady, the author of the article :)

          • Arkady Shapoval

            I don’t shoot anything serious on the mirrorless.

            • Ruslan

              What does serous mean?

              • Ruslan

                serious *

              • BB

                This means that serious commercial projects are filmed with a DSLR. But to take pictures of flowers in a flower bed - here, yes, a mirrorless camera, especially with a small matrix, will be more convenient.

            • grandfather Fedor

              Arkady, today a UPC with EVI in the professional field in which niche can or even have advantages?
              I now see only the field of training "photography", and shooting video with a camera.

              • BB

                Shooting macro, as an option - you can see the depth of field, in combination with a smaller matrix - already good + more convenient manual focus with an increase in the selected area.

                I myself shoot a macro on an old ultrasound with 1 / 1,7 CCD-matrix + macrolens. It turns out easier and faster than a DSLR. If you stick an inverted G-44-2 there, you get a good macro, but then you need good light.

        • Andrei

          But what about Anton Martynov

          • Peter Sh.

            I have no honor to know this.

          • Lynx

            To be honest, I really don't see any of his more or less interesting or suitable filming after his “sale to fujiku”.

        • anonym

          Maybe because you are shooting competitions? Still, the autofocus of mirrorless cameras does not reach the DSLRs a bit when shooting dynamics. But in other genres of photography, such as portrait, landscape, subject, many famous photographers are already switching to mirrorless systems (Sony, Olympus).

          • Lynx

            and why Olympus? is there a DD like a soap dish?
            I look at him from time to time, but it is worth seeing some examples of otographs, as the whole peeker beats off.

      • BB

        Modern cars are also packed up and down with electronics. So let's take the windshield from the car, put the display and camera. It's the same thing, why are there extra analog elements?

        • Ruslan

          Already do) You are behind the times.

      • BB

        And yes, the rear-view mirrors are also in the trash - this is the last century!

        • Ruslan

          And this has been practiced for a long time and quite successfully) You are specifically behind the times.

  • Alexander

    Arkady, you forgot a very important aspect of the lack of EVI - it is terribly buggy in cold / frosty conditions. If the response speed is already low, then you will generally suffer, we do not live in the tropics. Plus, after analyzing a lot of information on this topic, I think that EVI will be extremely uncomfortable at night or at dusk. What is there to look at? On noise, no on NOISE? In general, the key phrase of the article is “in the future”, IMHO it is too early to talk about EVI as something serious.

    • Arkady Shapoval

      Not forgot look

      Logs at startup or at low temperatures (may be fixed in the future)

      • Alexander

        Oh, sorry, I looked through the article fluently. =) Honestly, obviously not in the near future, and not even in 10 years, because manufacturing technology and the principle of operation of displays involves glitches at low temperatures. A radically new approach is needed.

    • Ruslan

      Can I have a list of cameras in which the EVI is buggy in the cold? It doesn’t fit in my mind why it should be buggy. Once upon a time, the same nonsense was said about touchscreen phones. But for all my life I have not come across a phone in which the screen somehow unusually manifested itself in the cold.

      • Alexander

        You were not visible in the cold. I'm not talking about a 15-minute walk with a phone in my pocket or taking out a camera - click and put it away. I'm talking about long-term work in the cold at minus 10-25. It's not like EVI, there you freeze through and barely move.

        • Ruslan

          Maybe you will not decide for me whether I was in the cold or not? Maybe this is you shit shitty devices, or do not know how to use them, because of your not smartness?

          • Alexander

            Well, maybe you will not assume what devices I have and whether I can use them or not. And it's not for you to judge about my cleverness, you don't know me. Judging by your ridiculous conclusions, you are narrow-minded, and there is nothing to talk about with such.

            • Ruslan

              Well, you allowed yourself to decide that I had never seen a frost. Why can't I?
              But it seems to me that you are not far off, and you don’t know how to use equipment.

      • Anatoly

        Yes, there is no such list)
        Because no one is buggy in the cold (and why on earth would EVI be buggy at all in the cold - it’s more likely that the JVI should be buggy, plus fogging when temperatures change)
        How many cameras I had with EVI - I have never met that the behavior would somehow change from frost ...

        Only in this article for the first time I read this absurdity ..
        For sure - the JVI apologists agree to suck and invent any nonsense right on the go, just to somehow try to oppose the Zhigul Cruiser ..

    • Ruslan

      And about what to look at night. The answer is even simpler. To the same as in the JVI, to the black rectangle.

      • Alexander

        Yah? I have been doing astrophotography for 2 years. Through the JVI with 35 1.8, I can at least somehow compose the frame, through Live View you can only adjust the focus on the brightest stars. EVI is not far from him. Ruslan, well, do not talk nonsense. =)

        • Ruslan

          And I’ve been doing photography for 8 years and worked for two years as a TV operator;)
          He shot on Nikon 5100, 800 and on Olympus EM5. At all the same, nothing is visible. If you do not see with your eyes, then neither on the JVI nor on the EVI, YOU will not take anything away. You need to look for a light source to focus. And here all the advantages of EVI are manifested in which you can increase the frame by 10 times and visit the spruce noticeable glare. Well, if it’s very tight, then a good spotlight solves all the problems, lack of light. Learn to use the technique first, and then criticize)

          • Alexander

            I do not need any EVI. For focusing, I use Live View in difficult conditions of lack of light, which has excellent magnification. A flashlight option is far from always suitable. It’s easier for me sometimes to use the backlight on the SB-910. Ruslan, you understand that there is no need to learn the majority here, smart and without you.

            • Ruslan

              That I see how smart))) Some write EVI to save energy, Others say that EVI does not work in the cold, and that it’s easier to use a flash when shooting at night))) It's just geniuses)))

              • Alexander

                I got the impression that you are a little “that”. The SB-910 has a focus assist illumination, it works far and amazing. Read the instructions, learn how to shoot, and don’t mix up an empty srach from scratch.

  • anonym

    I had a DMC FZ50, a good camera and almost everyone suited me, except for one EVF, because I have to shoot in the field and often the subject does not sit still, but moves and happens very quickly. I understand that the new generation of EVI is faster, but it definitely does not suit me. I switched to the D7000 mirror, maybe the viewfinder is too dark or my eyes are hooked, but it is still incomparably easier and better to keep the object in the frame through the OVI (in my conditions). And so, who loves what ...

    • BB

      I looked with this unit with two eyes: one in the viewfinder for cropping, the second on the object to capture the moment))

    • Ruslan

      Olympus came up with a calimarot sight, which in theory simplifies the shooting of distant or fast-moving objects. I am writing in theory. Since I have not tried it. But the fact that it is unnecessary to look at the viewfinder is already interesting.

      • anonym

        Here is the sight, about which you “have not tried”, simplifies the hit, and even then with optics it is much better than it. In any case, at a distance of 500 meters. But in general, it would be nice to take a couple of literacy lessons.

        • Ruslan

          It's funny when a person who writes nonsense, tries to teach someone else))) I advise you to graduate from school to start. and then argue with uncles)))

          • anonym

            Dude, don't forget to put commas. A reflex sight, by definition, gives only the aiming point, and is convenient for aiming ... Even the frame border cannot be determined. And if you shoot offhand, defining framing “by experience,” then what kind of viewfinder are we talking about? And I do not argue, just illiteracy hurts the eye!

  • anonym

    “But over time I felt all its charms and radically changed my mind.” Not a lot for the time being with charms. For example, I will change my mind, "when everything will be corrected in the future," but for now JVI rules.

  • Andrei

    My eyes hurt from EVI and for me this is a defining shortcoming

  • Michael

    "The same thing happens when you bring the camera to your face in the bright sun, while nothing is visible in the EVF for a while, until the eyes make accommodation."
    Eye accommodation - the ability to clearly see objects at different distances from the eye. Those. in this case Maybe this is better: "Physiological mydriasis is the normal dilation of the pupils in low light conditions, for example, at dusk."

  • Dmitriy

    JVI. You don’t have to invent anything else. You need to see what you shoot and see in reality, and not driven through the processor. Soon we will make children through the Internet, because there will be no time, no energy, nothing for reality.

    • Ruslan

      Take a film then, there is no processor.
