Pretty good if you can handle some minor annoyances
on August 16, 2015
This is a great lens by any consumer standards, and while not as great as others say, still a good lens by professional standards. Given the price, all of the following issues can easily be excused, as many more expensive lenses have the same problems. This 22mm lens's main issue is vignetting. There is more vignetting with this lens than with most zoom lenses I have used. Mid-range priced zoom lenses like the Sigma 17-50 f/2.8 tend to suffer from vignetting at the wide end, but this 22mm is even worse. Secondly, the focus on the 22mm is just weird. Maybe it's just my copy, but the electronic focus ring doesn't turn very smoothly, which combined with the EOS-Ms slow AF system and annoying lack of a AF/M shortcut switch, is pretty annoying. This lens doesn't have the AF/M switch that larger Canon lenses have, meaning the focus mode can only be controlled by the software on the camera. Overall this is a great general use lens for the EOS M. It is very sharp and despite its issues the EOS-M and 22mm combination will still outperform any point-and-shoot camera and provide entry-level DSLR quality results.
