Quote:It again is clear (to me at least) that the way you guys approach the MFT tests with the sharpening makes for problematic results that no one really can evaluate.
The sharpening exaggerates sharpness, and will not touch less sharp results, exaggerating the difference in corners and center, and also skewing results twice when comparing for instance how that Nikkor 14-24mm f2.8 did on 24mp.
I also wonder if the R-ness of the 5DS-R also brings its own part of the problem, here. Fake sharpness from "no" AA-filter skewing results up until the lens acts as AA-filter (corners).
Something worth investigating?
The 50mp versus 21mp results do show part of the sharpening issue(s). The 50mp extreme corners getting lower results than the 21mp extreme corners.
In essence - you want us to process images in a way that no user would do out there ... sorry - won't happen.
If you think that the charts would "look" any different - hardly - we would simply adjust the scale accordingly.
Yes, the numbers would be different but the numbers ... well ...
I can only repeat again that we tune reference images to neutral sharpness which Imatest identifies are neither over- nor undersharpened. That amount is less than the default sharpening.
