Since I know nothing about what cameras you used to use, I can’t argue with anything you wrote about how much better your mirrorless camera is for you, but it’s nonsense to apply those comparisons to a different brand and model, such as my Nikon Df, D750, or better yet, a D850 which I don’t have - yet.
That it works with your camera/lens does not mean it will do the same on other brands and models, such as my Nikon or Leica. Some of my old Leica lenses are limited by their lens performance, and mounting one on my M8, or M10, or the new M11 will not improve that. Lenses have improved over the last 50 or 100 years. Going from 8, to 100, or 1000, or 10,000 megapixels will not improve on what the lens is capable of, beyond the limitations of the lens.
I think again, this might be true for you, but not at all for me. My old lenses are limited by the lens performance, not by which camera I mount them on. My old lenses on my newer cameras don’t suddenly improve, but if the lens is capable of better results than when it was used on a less capable camera, yes, that will show up. One of my lenses that works fine on my LEICA M8.2 will likely work better on a Leica M11, because of the camera. If this is what you mean, I agree with you.
I agree with you - more pixels can result in a larger and more detailed image, if one is willing to pay for this in other ways. If someone gave me a Leica M11 tomorrow, with the 60 megapixel sensor, I doubt I would be using that capability. (Not to mention I think the raw file would be too large to upload to the DxO Forum.)
I’m not having any issues with auto-focus. My camera locks on even in poor light. Might it be an issue sometime? I dunno. But my Df and both my D750 cameras lock on just fine. Better tracking software like for shooting birds might help, but that’s true regardless of what type of camera is used. I don’t do that kind of photography very much - if I did, I would likely buy a D850, despite the size and weight. But for what I do now, the D750 is fine, and much of the time my Leica is too, but not for follow-focus. Rangefinder cameras were designed for other purposes.
I agree with the first part, more pixels can help in many situations, such as landscapes and bird photography. It’s meaningless for street photography, and then there’s the question of how many megapixels is enough? 24, 50, 60, 100, 500… How many megapixels do we need? As for me, 16 and 24 is plenty, and I used to be satisfied with 8.
No argument here, but PhotoLab DeepPRIME works on any image in raw format, for any camera it knows about, mirrorless, dSLR, or rangefinder.
No argument. My older Nikon DSLR cameras improved with auto-focusing every time a new model came out. My D750 is not as fast at focusing as a D4 or a D750. Five years makes a big difference. It’s the photographer that makes the difference, not the camera. For me, for my whole life, it’s been “use what ya’ got”.
I won’t argue, but I disagree with “without limitations”. Over time, cameras usually keep improving, and we then think about the “limitations” of the previous camera. This applies to all products. As for me, I accept whatever limitations my cameras have, and work around them. A rangefinder camera is totally un-suitable for sports photography, but in college I was out on the field with my Nikon SP photographing football games. I got my photos, and they got printed in the college newspaper.
I did get my chance to try out a Nikon mirrorless yesterday, and I hated it. The viewfinder looked like a tv monitor inside the camera (which it was!), which is nothing for me like seeing “live action with my eyes, not digitized”. There were other things too, like when I started to “pan” with a 24mm lens, and felt I was getting dizzy. I tried it today with a 24mm on my Nikon Df, and all was fine. Between all that stuff and focus by wire, these new cameras are too much of a step down for me. I’m sure they will improve, so I’ll try again, as I’m curious.
Anyway, when you write about how much better your experience was, that’s you, with your camera gear. Obviously you and your mirrorless make a very good match, and that’s great. It’s good that you are so pleased with it.
