    The whole difference is in approaches, some fall in love with cars, someone grows flowers in the garden, someone has a happy violin. A person is a sentient being - if he likes some kind of camera and a person enjoys using it or, for example, like the aforementioned lens - for a long time reveals its capabilities, then he enjoys life and this is wonderful. Another thing is that it is very difficult to enjoy work :), sometimes it is almost impossible. At the same time, such “unrequited love” with enthusiasm for becoming “work” also makes life complete and allows the individual to develop, and not degrade. Lying drunk under the fence in your stool is naturally much easier than trying to create at 1001 weddings, which happened according to the scenario of the previous 1000 :) Maybe you should do Psychology if the photo seems to be studied and then the latter will take on new facets :)

    Pentax is 100 years old, hello. When I was choosing a camera for myself, I was guided by the criteria “more than once”, survivability (all-weather), the materials from which I collected.
    And so, since the age of 11 I have been walking with a k-5, during this time he went with me both fire and water, in the literal sense. Just the way the officers looked at me after the training ground, when I washed away the dirt and gunpowder under running water - it was worth taking it. The guys even dropped their cigarettes.
    During this period, I took Canon, Sony, Nikon into my hands ... But all this did not just seem flimsy, they actually did not give me that joy, emotions that I got with my first digital SLR.
    At minus forty-three, Sony said it was completely discharged, and Pentax worked with a bang for five hours. Five hours for which the event simply ended. For which I had to run several times to the field forge, to the forge (where I burned the back of the gloves, just blissfully warming my hands).
    Where the canon got wet and refused to work, pentah ... I would have worked with a bang, but I did not take it with me. This baby is still lying nearby, proudly flashing a sticker from one of the security services. And now I only take him with me. Maybe I would have changed him, but for my soul and business, he completely suits me. I do not shoot weddings, companies, in the studio - I shoot what I like and when I want (including the period of service).
    And yes, no matter how much I love pentas, I consider the K-70 a freak. I think the less moving parts, the better. We changed the usual ergonomics. And generally speaking.

      Already wrote, but think twice. Sigma just recently officially announced that it was discontinuing the production of lenses for the Pentax system, and Tamron, most likely, would no longer do this either. The reason is not profitable, the demand is too low. Few people use Pentax. And Sigma is going to put all his efforts into the production of lenses for mirrorless systems, believing that they are the future of photography.

    The right color and good color are two different things.

    Arkady, I think what to talk about color when a lot of people do not understand at all how the camera works with color ...
    Do you have any educational program on this topic?

    Any camera has a color gamut that fits into the selected color space, amateurs most often use the ancient sRGB.
    Any matrix, within the framework of its settings and hardware, tries (or not) to write the information received as accurately as possible.
    Pros and amateurs have different requirements.
    Pros need a camera with accurate color reproduction.
    The amateur is more colorful to acidity, and accuracy is not needed at all.
    Profi wants to get a predictable result at the output, he winds up the rest.
    Here are the manufacturers and began to twist the saturation equal to saturation from 3% -5% to 15%.
    Hence the endless flame about Skinton. It’s easy to understand what was really difficult at sunset, but you can see greenback or carrot on the skin), especially if it was not in the source data.
    Further, the paths of inexperienced lovers again do not coincide with the pros.
    The pro looks at the result of imatest or the like and already knows where and how the camera will lie by color or saturation.
    Because any subject - tops, landscapes or portraits - is a special case.
    An amateur scornfully scoffs and does not understand the test (well, it’s difficult there, all sorts of numbers!) Spends a lot of time checking each particular case.
    The same thing about lenses, the pros look MTF, the noob takes bricks for a long time and writes nonsense about opening the lens.
    The evolution is obvious from here:

    There is no favorite camera. There is no favorite lens. There is no favorite system. Most like Nikon and Canon. Question 'Nikon / Canon?' is a kind of photographer maturity detector.

      When talking about a camera, it is not customary to talk about color gamut. Glory to T-stu, already at least not "colorful", already the megaprofi spied on the definition. Color gamut is a characteristic of an output device. An input device (camera sensor) has a spectral response.

      Each element of the matrix generates some value. This value indicates how many photons the element has caught. He can catch them with a certain probability for each wavelength - this is the spectral characteristic.

      There are an infinite number of spectra that a given specific element with a given specific spectral characteristic can reflect the same value. It can be a monochromatic radiation source, a combination of them, or a whole spectrum - it doesn't matter. On the other hand, we have at least three types of elements, so each of them will react differently to this spectrum. Therefore, it is impossible to talk about color gamut - within a certain range of wavelengths, each element of the matrix will respond to ALL spectra.

      After debayering and interpolation of the obtained values, we will have three RGB values ​​for each image element. They are dimensionless and can mean anything. They need to be interpreted in some way. The interpretation is handled by the camera profile. It is either an embedded profile that is used internally by the camera to create a JPEG image. Or converter profile. In general, the conversion is performed according to the RAW -> XYZ -> sRGB or AdobeRGB scheme. The output profiles already have a color gamut - these are some ideal monitors with certain characteristics. We can bring to them the triples of values ​​taken from the camera. As a result, we run into the output device, in its color rendering capabilities. HOW you interpret the values ​​depends on the profile. You can wind up the profile in any way you like. It can be some kind of relatively simple matrix, it can be a set of LUT values, it can be anything you like - at least write your own converter for your needs. You can take photos of 16 million patches, adjust your profile to fit them - the matrix will fix all the colors in a certain way. She counts photons, she does not see color from the word at all.

        Sensors have a color gamut, I'll tell you a secret - it is measurable and usually superimposed on the color space.
        Therefore, if the sensor provides coverage within sRGB, it makes no sense to change the output format. But if the sensor is much better than srgb, the output format of srgb will simply cut off some of the halftones.
        Therefore, you need to know the capabilities of your carcass in order to choose the output format.

        Sensors DO NOT have color gamut. Color gamut is a characteristic of output devices. This is the definition. What the sensor measures, I explained above. If you find it difficult to understand, re-read it again. You can even several times. Do you even understand what color is? How does the eye work, how does the sensor work? Until I see understanding, real understanding - you are simply relaying a set of mantras without bothering with examples.

        The sensor issues a RESPONSE to the EMP in the form of a set of numbers. You have a specific spectrum of radiation - the eye reacts to it with a specific response from the LMS cones, which the brain interprets as color. And the sensor generates numbers, which are obtained after digitizing the voltage on the photodiode, which is covered with a light filter. And different situations may arise because the systems are different. Two different responses in the eye to two different spectra and only one in the sensor - the sensor does not distinguish between such spectra. Or one response from the eye and two from the sensor - the eye does not distinguish between such spectra.

        Interpretation of these numbers gives you color. Interpretation only. In principle, sensors respond to all spectra to which the eye responds. Only they do it in different ways.

        > Your enchanting nonsense that imatest measures distortion from flash and polarization made my day yesterday, today I'm without popcorn)

        This is your speculation. I talked about the fact that the shooting conditions are so different, and any devices affect the resulting image so much that I see no reason to talk about skinton or beautiful color. It will be exactly what you make it as a result of processing. I don’t know what you are doing, WHAT you are shooting, but neither color correctors nor retouchers ever worry about skin color, unreliable color, boring color - they create it themselves. Desolation of the theme of color is the lot of photo dochers and techies. This is not art. This is not a photograph. This is a photo doc, the same as audiophilia, when not music is important, but per se sound. You can do this alone or in groups, but you do not need to poke your mantras under each message. This is not healthy. You have a schizophrenic approach, you simultaneously declare that the camera is an instrument and what it is - it doesn’t matter at all, but only the color rendition is important, and better 1DS III and 5D II or whatever you advertise there didn’t come up with anything.

        Yes, if you remember where these RGBs came from, and that in different people, cones register different ranges of the spectrum - all these standards are tied to the hospital average value. To which the printing-display devices are also attached. As a result, it is not possible in principle to achieve that for EVERYONE in the end the photograph displays the real color. Maybe someday color photography will take a step forward, registering more than 3 bands of the spectrum, but so far it has not.

        The perception of the image depends on the viewing conditions. Perception is influenced by the size of the image source, the presence and position of the light source in the room. The sun came out from behind the curtains - the color temperature crept. Moved the lamp closer to the monitor - the same thing. More monitor means less impact and vice versa.

        In people, everything is just about the same, if there are no diseases. Whoever painted the standard curves in the 30s didn’t really have to average them over the observers. Almost identical results.

      For what? Now, except for the obstinacy of this constant and unproven? It’s possible some images, better in RAVs, some development results. Only artistic images, not this typical crap of yours, when you take a picture of a hut, some bush, or headphones on a synthesizer. ALL PICTURES that I have seen on the photo doc forums are disgusting. They just remove anything, show them in different ways, sort through profiles and try to make out details. In these pictures there is no sense, there is no artistic value, you can not take them to the exhibition, you will not sell them to the customer. These are just stupid photos of dull lovers in which there is nothing at all but an abstract and comprehensive color.

        The most interesting thing is that imatest works with RAW files using dcraw. And with standard profiles, which are generally, in my opinion, adobian. That is, the most important stage - the interpretation of the obtained RAW-values ​​is at the mercy of the standard profile, made by some sort of colorchecker. Well, what can then be compared at all? What kind of objectivity are we talking about? Changed the profile on the same sensor - got other results.

Because the first one! Because I taught! Because I fell in love with the photo!
