Verdict
Since the release of the EOS system we have seen several updates to Canon ultra-wide zoom lenses
but they didn't really care about their fix-focals in this range ever since their initial
release back in the early 90s. The Canon EF 20mm f/2.8 USM feels a little dated by now - less
so regarding its mechanical qualities but optically it isn't really something special anymore.
Most good quality zooms can match its quality by now. The fix focal lens can still
convince regarding distortions and CAs. Resolution-wise it is still a good to very good
lens for sure - just not more than that. Vignetting is a little on the high side at f/2.8
which is a little disappointing for a full format lens tested on an APS-C DSLR. So unless
you require an affordable, large aperture lens in this range there're few reasons left to favor
this lens over e.g. the Canon EF 17-40mm f/4 USM L.
