 p.4 #4 · Any 1 to 1 comparisons of A7CII to A7CR? | |
Hello tzhang4284
You have two posts in this thread where you claim things an a way as they were absolute truths. They are kind of misleading and I have to comment. I have divided your posts into paragraphs.

I had the Sony A7RV and still have occasional access to a Sony A7C that belongs to my mother for her travels. I would say if you want to use the small Sony lenses, Samyang and/or Sigma lenses - go with the Sony A7C II or even the original Sony A7C. None of those lenses are good enough for the 61mp Sony sensor.
It starts right there. What is "good enough"? At page 3, post 1, I have showed the center part of images taken with the 40G using firts the A7C and then the A7CR. The resulting resolution power increases from 68 lp/mm to 96 lp/mm when switching to the later camera. granted, that is in the center of the image but you do get higher values also at the borders.
Again, the used method is not as scientific as when using a software based method but my results correspond quite well with what sites like Lenstip and other get.
In what way, or for whom, is this "not good enough"
At one point I had both the 40mm f2.5 G which is probably Sony's best small lens and the 35mm f1.4 GM and 50mm f1.2 GM and the image quality differences are noticeable. If you use a GM lens on the A7C, it looks and feels comically unbalanced.
Of course there is a difference. The sharpest Sony lens (at short distances at least) is the 50/1.4 GM. It reaches 105 lp/mm (my test).
Comically unbalanced? You mean in a way reminding about an A7RV with an 880 gram 24-70/2.8 GM zoom?
Only case that the Sony A7CR might make sense is if you plan on doing a lot of landscapes and want to use compact Zeiss or Voigtlander primes otherwise you're better off with the A7RV like someone else said.
I have found it to make sense with other lenses as well. But of course, what makes sense is a personal thing. I have no problems supporting the 50/1.4 GM with my left hand holding the camera with my right. The weight difference between cameras doesn't matter much when shooting. What matters, in my experience, is how you hold and handle the contraption.
If you are better off with the A7RV is a matter of what you shoot, no?
In using the car analogy above, it would like a two seater car with a really big engine but not the right wheels or transmission and aerodynamics to actually drive it fast.
Funny put but far from a fair comparison. But I guess you knew that when posting.
and later
Individual tolerances differ - I would rather use such a lens with the A7RV style body. I had the 35mm f1.4 GM, which is smaller than the 16-35mm GM II, on the A7C and it still didn’t look right and felt unbalanced - a grip helps but it makes the camera much bigger.
I think for the A7C style bodies, there’s only a few AF lenses that balance well from a size perspective - the ones i remember are: Sony 24mm G, 40mm G, 50mm G, 28mm f2, 35mm f1.8, 50mm f1.8, 55mm f1.8, Sigma 24mm, 45mm, and 90mm, and the Samyang tiny series. None of these lenses are as good as the GM lenses and if you did a side by side comparison at 61mp, the weaknesses are there. I think all the above lenses would work well on a 24mp body.
For MF, there’s a few more options that would work well at 61mp and balances well: Zeiss Loxia series and Voigtlander 35mm and 50mm APO come to mind....Show more →
All that is more of the same. The beginning is correct. The 50/1.4 GM performs worse at the corners when using a 60MP sensor than it does in the center when using a 24MP sensor.
So sure, the acceptable limit for what our eyes and minds can stand differ.
To sum it up: I think many of your statements are too sweeping, too much of black and white.
