Just curious if the 85L will perform better on the 5DS downsampled to 22mp compared to native 5D3?

 

Wide open of course

 

Has anybody done these tests? Hopefully Photozone will review this lens on 50mp as well soon

 

I'm looking at every possible way to improve the image quality of my 85L

a look at the current 22mp MTF:



It shows us that the lens is pretty sharp wide open, in the center. This will mean that: yes, you will get more resolution in the 50mp file than in the 22mp file. The borders, probably not so much more resolution. But those generally are not that important wide open, since the DOF is small.

 

You of course will not get better IQ from the lens. However, you will get better IQ from the sensor, noise wise (The 5Ds has less intrusive pattern noise), and will be able to make bigger prints and stand up close and not see the individual pixels (but one normally doesn't stand up close to bigger prints).  Why one would want to downsample to 22mp, I am not clear about. That seems a time-wasting exercise?
