Originally posted by biz-engineer Actually, from the experience of using Pentax DFA glass (zooms), I am not so sure now if 61Mpixel sensor is the best choice. Glass has limits to how good it performs (aberrations etc.), and sometimes more megapixels with the same glass is just a waste of memory space. Maybe there are other than 61Mpix sensors that perform better overall, such as faster read times, better dynamic range. Looking at the second hand market, a number of A7RIV for sale used, no sure why, maybe upgrades to A1 or medium format, I don't know.
It is hard to say. There are also other issues with RIV, like weather seals and freezing up, and what more, not sure since I’m not that interested. Also A1 is told to be the ‘best’ one can buy. Many advantages over that model if one has enough money
those top models from 3 brands seem to go for 45 mp. But wait for 80 MP sensors. Just around the corner…
So, if Pentax will manage to do their magic with 61, with enough speed and very good DR(still with so many MP) it might not be bad move.
That said, it is a lot of MP. But it seem to be where we are heading all in all..? This might be why there are some engineers with idea with smaller MP FF around. I have no idea what will it be. I do like 36 MP on K-1, I like 26 MP with K-3III. Lower than 36 on FF does not attract me. Why. Because K-3III is ‘as good’ or even better, that is why.
