Jul 28, 2015. 1. About a week ago I was asking about the EF 20mm f/2.8 USM that I was considering purchasing. I didn’t seem to get a lot of first-hand experience feedback though what I heard was pretty mixed. Someone suggested that the lens was really decent if you know how to work with it.

With light weight and size, this may replace the Sigma 18-35 f/1.8 as my favorite lens.
