Canon EF-S 10-22mm f/3.5-4.5 USM SLR Lens for EOS Digital SLRs: Customer Reviews & Product Details

I am very pleased with this lens. Images are sharp all the way to the corners. I can't see any chromatic aberration. Recommended.

If you like an artistic style and really want to get a wider picture, then you will certainly not be disappointed with this lens. The color and clarity of this lens is fantastic and it's a blast to use! Just be sure to practice with it first if you take shots with people in it...as it will distort.

So much fun and a must have for any non traditional photographer!

I purchased this lens for my Canon 40D and have been very disappointed with the extremely soft images throughout the focal range of the lens. Yes, you can get a great wide angle shot on 1.6 factor cameras (Rebel, 10D, 20D, 30D, 40D and 50D) but the shots look like they were made with a barely acceptable point and shoot camera. I had hoped for much better from Canon. I've sent it to the factory for repair/adjustment 3 times, and it's always come back the same, with a lack of definition, barely acceptable saturation and no "pop".

I did some test shots comparing the Canon 10-22mm with Sigma's 10-20mm, and the Sigma won by a mile, with at least twice the sharpness and saturation. Why buy a pricey lens only to get mediocre images--and my wife's cheap compact Fuji actually takes better images than this lens.

I love shooting with Canon, but this lens now just sits in my bag, and I don't even feel good about selling it to someone else. Canon should never be putting out a lens with such obvious inferiority, especially at such relatively high cost. I don't know if mine is simply a bad lens, but I'd have expected that Canon's repair department would have corrected it with its 3 trips into the factory. Right now I just have a very expensive paperweight. My advice: Only buy at a local store where you can test each individual lens before buying to make sure you get a good one.

Here's my personal pro/con list after I took this lens out to DC for a weekend.

Pros:
Extremely wide - WOW!
Lightweight. Can't believe how light this. Probably the lightest among wide angle lens.
Interesting effects can be achieved which is normally difficult in normal zoom lens.
Fast focus, and very quiet.

Cons:
My most expensive lens. For sure will take a bite out of your wallet.
Bad lens distortion wide open 10-12mm. Can be corrected slightly in photoshop, but sucks for architecture because lines become bent.

Overall, a great lens for traveling. One of my favorite lens.

This lens is so much fun to play with, and really gives a unique perspective to your photos. Would definately make this purchase again!
