Canon EF-S 10-22mm f/3.5-4.5 USM

Review Date: Feb 6, 2005 Recommend? yes | Price paid: $690.00 | Rating: 7 

Pros: Very wide, distortion well under control, neutral colour cast
Sharpness and contrast are lacking, EF-S mount, not exactly a compact lens, pricey, no hood included

I don't know how difficult it is to build a great wide angle, but this lens falls short of greatness on a few counts.

Cons first;

1) For the exorbitant price, you don't get a hood and only a lousy cardboard box. C'mon Canon, even my $180 Sigma comes with a nice padded case and hood!

2) Optically decent, but not great, definitely not in the 17-40L category. I've tried 3 different copies and all were disappointing at one focal length or the other. Unsharp wide open in the centre (all 3!) and really needs to be stopped to about f8 before it gives good performance. 1st lens I tried had noticeable CA in the top-right corner that wouldn't go away even with stopping down.


1) Great WA! Has made a convert of me to WA shooting for sure.

2) Typically quick USM focussing from Canon which I now refuse to live without.

3) Build quality is very close to 'L', very solid and robust feeling. Zoom and focus rings are smooth and don't jiggle.

Overall I would recommend it, but the optical quality was a bit of a let down, at least for the copies I tested.
