I was surprised to see that there was not an archive for this great little lens. An older lens that was released in the 90's, but with great optical performance and a nice feature set. One of Canon's initial attempts at an UWA lens and the little brother to an L lens with the same focal range.
Not as wide as many of its EF cousins (nor as long) but above average build quality, metal lens mount, distance scale, internal focusing and full time manual focusing through the inclusion of a fast and silent ring USM focusing motor. Also a slightly faster aperture offering than many less expensive wide angle lenses with f/3.5 on the wide end and f/4.5 on the long.
Hopefully starting this thread will prove that there are a few people still out there using this hidden gem of a lens. I will post some recent samples that I have taken to kick things off.
