At first, I wasn’t sure I wanted to spend more than a thousand dollars for this lens but after comparing it with 2.8L IS, I decided to go for f/4L IS, since I rarely take a tripod especially travelling and vacations so size and weight are important factors for me. Basically, this is the lens that I can put in my purse everyday for a hand held shots. It’s just light enough to carry at all times. I had this lens for about a month now and I took it on a cruise to Alaska, and this is just simply amazing! Sharpness at wide is phenomenal and it has excellent image stabilization! Canon’s 2.8 is obviously great lens but it doubles the weight and you need a frequent use of a tripod, and that would be my excuse to not carry it.
I took a lot of photos handholding at 1/15 and photos were very sharp! AF is also very fast and accurate even in dim light.
Image stabilization is very important for me! I would strongly encourage anyone to consider buying the IS version, although it’s more expensive, it is still worth the difference.
Here are a few unedited examples of images and all shots were hand held:

Canon EF-S 10-22mm f/3.5-4.5 USM

Posted by Shamn on 10/06/2009

Suggested Retail Price: $829.99†

I purchased this lens for my Canon XSi and I am extremely satisfied. The build quality is pretty decent and optically much better than Sigma. I have owned this lens for just over 3 months. It’s really my first “true” wide angle lens for my DSLR and I couldn’t be happier. There is definitely distortion, if the subjects up close, it really does distort but by saying that, sometimes I don’t mind it at all. It gives some weird effect to the photos especially taking animals and some weird stuff. Other thing too, the vignetting. It’s really noticeable at wide open at 10mm but you can always correct that very easy which isn’t a big deal for me.

The picture quality is excellent for an extreme zoom, focusing is really fast and lens alone is compact size and very lightweight. I shoot hand held most of the time and still images are very sharp, how much more when you mount your tripod to your camera. Although I miss IS, but USM makes focusing fast and quiet. Great for landscaping photography especially with those panoramic photos. If you have a good flash in indoor low-light photography, you can capture very sharp and perfect images.

Although a little pricey this lens has exceeded my expectations. Bottom line, this lens takes an amazing photos and anyone who has Xsi should think about purchasing one.  It’s worth every penny.

Here’s a few unedited examples of images using EF-S 10-22mm lens. [All shots were hand held.]
