The ultimate test of course is that we need some folks to post some pics from other lenses. I just went back and found a good example from similar circumstances to my previous posts. However more even lighting and I think more correct exposure, The others I posted were very saturated and probably 1 stop or so under to that end. I can detect NO fall off in ANY corner. I'm not sure if I'm beating a dead horse here or if it is still of interest to some. I'll post again if anyone comes up with some other pics.

I took a look.... The Zeiss Biogon 28/2.8 vs the Leica ASPH Elmarit 28/2.8. By looking at the charts of MTF at full open ( F2.8): It looks like the Leica lens is far superior.... less fall off. At F5.6 .......same conclusion.... I do not read these charts well, so I could be wrong, but it appears the Leica lens is a better performer for light falloff in the corners...... I also looked at the F2 ASPH Summicron......The Leica lens still looks better...... So, if one were interested in vignetting being minimized, Either Leica lens would outperform the Zeiss Biogon.
