next PZ lens test report: Canon EF 20mm f/2.8 USM
[quote name='Klaus' timestamp='1351019239' post='20689']

This is normal.

I would be very surprised if slrgear performed tests on a flat plane rather than on the focus field. This would be naive testing (of defocused zones). Manufacturer MTFs are also provided based on the focus field.


"Normal" as in "expected and desirable for a lens". I can understand if it's normal for this particular model.

By the way, for the sake of completeness here's another review of this lens. The verdict is unsurprising.

By the way, I was bored today so I compared the results with those of the old Nikon 20/2.8 D, and it looked so much better in comparison (of course I didn't compare exact figures, just the resolution bar heights and general impressions), despite being an old design with mechanically dated implementation.
