    Good day. Please tell me, are these minuses still relevant for EVI, three years later? Today, the question is between Canon 800D and Canon M50. In particular, Inertia is concerned, in general, and especially in low light.
    Thank you in advance for your reply.

    Good afternoon!
    Thank you for the article. I’m thinking about switching from a SLR to a mirrorless one, the viewfinder is the main stop factor.

    Your article is good, but very important information is missing since you are making a comparison. You write: "As a result, there is a huge lag between turning on the camera and displaying the image." Is this lag in milliseconds or seconds? Similarly with the inertness of EVI. How much to wait?
    I mainly shoot reports and if the lag when switching on or a sharp change in composition is more than a second, then this is already critical.

    Thank you

      Very much depends on the specific camera. There are seconds, there are milliseconds.

    And there is one more nuance, there is little to say about it, When you use a mirror with a mirror from your hands, you trim the camera with both hands, and turn my stench on your knees. With mirrorless cameras, with a video through video, your head will serve as a third point of support, so kindly stabilize the camera.

    EVI is also becoming even more inhibitory in the cold?

    Thank you for taking the time and for putting in the effort to research and write these articles. They have clarified several technical points which I was interested in or concerned about. Plus these articles are interesting and motivate me to read more of them and to research other technical areas as well.
    I was lucky enough to be researching about focus sensors in the Nikon line and one of the online articles I ran across linked to your site. I've managed to use the web based Google Translate to enable me to read your articles. My Android phone also has a Google Translate app which I use to translate the text in the images. Translations are not perfect but the intent is (almost) always clear after a moments thought.
    I own a D7500 and initially was interested in the D850. After about a year of taking in more information and after the Z7 had a Firmware upgrade to version 3.0, I'm seriously thinking about saving up for a Z7 instead (unless a Z8 is soon released).
    Thanks again for the excellent articles. Best wishes in staying safe during COVID-19.

      It's unexpectedly to see the foreign reader in the Russian language site. Nice to meet you, Ross Tucker! About a full frame camera, l would prefer D850 instead of Z-series. In my opinion COVID-19 it's the global fake to make new financial economic world. C-19 is no more dangerous than ordinary flu.

    EVF is extremely poorly suited for people with low vision. Few cameras allow, in principle, adjusting the diopter correction to obtain a normal image if the operator is wearing glasses. Usually there is not enough adjustment range. In addition, many people with poor eyesight, even after relatively short viewing of the image in the EVF, begin to ache and watery eyes. I have myopia minus seven, tried to shoot with a variety of cameras with EVF - the result is sharply negative.

      Vision -2 / -3 + astigmatism, I put on contact lenses for long surveys. I did not experience any problems with any viewfinders. Although I prefer JVI.

        not so simple. I knowingly indicated the degree of myopia. and I can add that with such a high myopia, I already completely have no accommodation. so lenses or corrective surgery will only add to the problem.

        For minus seven I will not say anything, for my wife minus six - she takes off normally in the lenses. Of course, if you look at the monitor / viewfinder / phone all day, your eyes get tired, but in any case it is more comfortable than wearing glasses.

    When using OVI in DSLRs, fast phase focusing takes literally milliseconds. When using EVF, the contrast focusing mode is very slow. Takes 1-2 seconds.
    The rest of the parameters, such as the shake from raising the mirror, do not even consider. The mechanical shutter itself creates sufficient movement.
    When using the ZM-6a with a converter * 2, on a sufficiently powerful tripod with a weight of 5 kg, I observe on the screen in live view mode (without raising the mirror), when the shutter is triggered, the fading oscillations of the image are 3 ... 4 sec.
    All information is displayed on an additional LCD screen.
    And of course I don’t want to warm the matrix and consume battery power.
    As you understand, I am for the JVI, although my vision is -4 and I am wearing glasses!

      And by the way, in connection with the retirement age, there is also no accommodation. I use several different diopter points for different situations. You have to put up. :-)

    "A strong advantage of EVF is the ability to see the finished result before the shutter is released."
    This is an advertising LODGE!

    Arkady, why don't you want to honestly write that before pressing the "trigger", on the screen and in the EVI, we see only an IMITATION of the future frame?
    (Some manufacturers of photographic equipment honestly write about this in the instructions, and warn that the photo may differ from what is displayed on the screen)

    I understand why some manufacturers and sellers are trying to trick us (to get a new camera in, despite the fact that my current camera shoots well), but why reputable photographers repeat this box, I don’t understand.

      You seem to have read inattentively. After the phrase you are quoting follows a text explaining some points.

      It is not clear to me how you read and skipped the whole section about it. The section is called “Is the finished result actually visible in the EVI?”. I wrote everything honestly and constantly supplement this article, it is unlikely that you have the right to write to me here about "advertising" lies :)

        In the first sentence of the section, you write:
        "A strong advantage of EVI is the ability to see the finished result before the shutter is released."

        In the penultimate sentence, you write:
        "Regarding small differences from the image observed in the EVF and the final frame"

        So we see the finished result before the shutter is released, or all the same, the images before and after the shutter are different ???

        Re-read everything again without pulling out phrases.

        For example:

        A strong advantage of EVI is the ability to see the finished result before releasing the shutter. But there are reservations.

        Or do you really something is not clear or do not agree with something? You can describe your thoughts and your experience, it will be useful to readers (I hope).

        If a person is convinced, then no explanation will help him. Though standing on your head, Arkady, just ignore such experts;)

        We cannot see the “finished result” until the shutter is released!
        Before the shutter is released, we see the IMPOSITION OF THE EXPOSURE which does not always correspond to the finished frame. (you yourself write about this in the same article)
        And this imitation is not a virtue, because in practice the exposure indicator and live histogram are more useful.

        Such phrases mislead people and make you believe in something that is not really there.
        And as we can see from your “FANS”, people truly believe in this.

        That is, sometimes the exposure corresponds to what will be in the picture. And those cases when it does not correspond, for example, with pulsed light, are described here. As described imitation. Still I can’t understand what are you leading here

        If you have the truth, share it. So far, I do not see in your words any conflicting data from my article. I see only a run over on EVI, while there is no objective approach yet

      since I was not given to shoot on the UPC and use the EVF for reasons of strong myopia, I will say that I see my canons on the display in LV mode - and I see a fairly exact similarity of what will then be in the picture. brightness (shadows and light), color, depth of field - everything is almost the same as it will be as a result. moreover, I adjust WB in Kelvin by looking at the display itself. (although, to be honest, I will say that the displays of my cameras are color-calibrated by me personally, which is not the case with conventional cameras)

    Hello.
    Question on EVI in Sony cameras. Along the perimeter is the display of technical information.
    Is it possible to remove all this in the camera settings so that only the bottom line with key information remains? Otherwise, it turns out that it is impossible to control the shooting process along the perimeter of the frame. Suddenly there is a photo rubbish ...

      Yes there is. You can remove everything at all
