next PZ lens test report: Sigma 20mm f/1.4 DG HSM Art ... on 21mp and 50mp
#3
I knew that visiting 4-5 times a day would pay off some time... But the main page gets no love again. Smile

 

(after finishing reading the review) Well, now we know. The borders and corners at the larger apertures (say, wide open and one stop down) produce similar absolute values on the two cameras - though on 5DSR, they're still worse - but because the absolute values in the center are that much higher, there is a very pronounced spread on the scale and the impression that the border and corner resolution is simply nonexistent (as some site commenters have alleged with regard to, say, the Tamron 35/1.8). 1 1/2 to 2 stops down, the absolute values begin to race ahead even at the edges. I think it's going to be a pattern from now on...

 

P.S. Here's a novel thought: could you copy a link to this review to the "Tested at 20mp" section of the Canon FF reviews? Because it's just that, two reviews rolled in one (BTW, isn't the 5D Mark II a 21MP camera? (which you mention in this present review).
