Canon - EF-S 10-22mm f/3.5-4.5 USM Ultra-Wide Zoom Lens - Black

I have wanted this lens for quite some time, but it was always $900! This lens beats the image quality of the 17-40mm hands down. When I found this on sale I jumped on it. Right out if the box I put this in my T3i and started snapping pictures. Here's the real deal on this lens; So most Canon cameras have a CROP SENSOR, meaning not full frame which is found in the PROSUMER level cameras ($1200 body cameras). This means that you should figure out what your crop factor is (mine is 1.6) meaning this 10-22mm will act more like an 18-30mm so you can't get as close as you think and as much picture in your frame when you print! On a full frame camera this lens is so wide that you often end up with black edges. THIS IS NOT A PORTRAIT LENS!! Subjects WILL be distorted closer to the edges! This lens does bend the image on the edges which mass this lens great for landscape photography! No IS is a downer but keep in mind that because this is basically a landscape lens, landscapes don't really move to where you need it. Great image quality! People complaining about poor image quality with filters on 1) need to understand what each filter is for and how to use it 2) there is a reason why BestBuy filters are $25 and Canon ones are $200!!! IT'S THE QUALITY OF THE GLASS!!! With that said, I have no problems with this lens and its a good buy!! If you want portrait get the 85mm, zoom get the 70-300mm, macro get the 100mm IS USM.

For advanced Canon digital SLR camera owners of the Rebel XT, XTi, XSi, or the EOS 30D or 40D, with the money to spend, this is an ideal ultra wide angle lens. You'll want to use it for building interiors, groups of people, or sweeping landscapes. This 10mm-22mm lens has the 35mm equivalent of a 16mm to 35mm lens. In my opinion, it is far better than equivalent models from Sigma, Tokina, Tamron, and experts say it is better than any equivalent digital Nikon lens as well. I would have rated it 5 stars, except for these disadvantages: (1) It is priced as high as a Canon "L" (luxury) lens, but it doesn't have the L's dust resistance or build quality (although the glass itself is top quality). (2) This (and all EF-S lenses) will only work on small sensor (APS-C size) Canon DSLR cameras, so if you upgrade to the Canon EOS 5D or EOS 1DS body, you cannot use this lens. (3) It has a maximum diameter aperture of f/3.5 which is not really fast enough for all low light situations without increasing your ISO settings. And darkly lit room interiors are a tempting place to use such a great lens as this. So far, it is my favorite Canon lens for my Canon EOS 30D body.

APS-C cameras give you great telephoto length but sometimes make width of composition difficult. If you have a large family group in a small room setting this lens might be your answer. Probably why it is also popular for real estate and architectural photography. I plan on using it also for travel landscape shots as well. Some shots at the 10mm range may show some peripheral illumination issues as well as distortions however most of Canon's newer camera can correct for this or you can use Canon's DPP software on raw images for correction. One point to consider is that if you are planning on using your cameras on board flash on the wide end of this lens you will observe a lens shadow for indoor photography. The easy workaround is to use an external flash such as Canon's 430 mounted to your cameras shoe and the shadow will be gone. I have been pleased so far with the sharpness of my images. Hope this helps your decision.

The only negatives I have about this lens is the price and some slight distortion. It's a little expensive, but I guess that's the price you pay for some amazing shots. The image quality is stunning. It's great for larger than life pictures (in the city surrounded by skyscrapers) and situations where the space is limited (a group shot in a small room of your house). Performs well in low light simply because there's hardly any motion blur from the wide angle. There is some slight distortion when you zoom all the way out to 10. Overall, great lens.

Most of my pictures have been experimental as I get used to this lens. I was so glad to have it as I like to do a wide angle when outside. I like including as much of the scenic as possible. This lens will enable the user to bring in more variety of color if it is there. I have never had a wide angle lens before so I am surprise by some of my success. Example, a brown dirt road in foreground, an old building and green lawn midway, and a blue sky with white clouds in the distance. Everything is in focus, not just one subject. Flowers can be included in the foreground of a picture to include more color and interest. Taking a picture of a curve in a road adds width to the area around the turn to add a little mystery in the photo. Still am trying to find scenics and subjects which will make great pictures. Sometimes need to get closer than you think and other times one can back off to get the broader view.

I bought this lens primarily for vacation and I also took along a nice f2.8 24-70 but I hardly ended up using it because of the wide angle worked great for me scenic shots. Did not really know how things were going to turn out until I got back and looked at them on the big screen but for the most part there was very little noticeable distortion when in the maximum wide-angle setting. Definitely a nice lens for the bag specially when wanting to get scenery shots or complete buildings or other items when in a city environment.

I love it. Amazing colors- I used to spend hours adjusting the pictures on Photoshop and now my pictures come out great- no changes need to be made- the lens does it all by itself. I’m a kind of a freak with the pictures; I always have my camera with me, no matter where I go. I’m not a professional photographer at all- but taking pictures with this lens makes me feel like one  It is a little bit expensive- but IT IS WORT IT!!!! The pictures are unbelievable. 10-22mm is the best for vacation; big buildings and house parties :) Hurry up and get it!

Bought this lens before I went on vacation and it never left my camera body and still hasn't. Ive used it for time-lapses, light drawing, architecture & landscape photography, and even portraits (at the 22mm focal length, so there isn't any of that fish eye effect). The lens is made with canon L quality glass, and you see that in the shots. I was shooting on a t2i and the images still came out amazing. Although I will say there is a learning curve to using a WA lens, and I'm still learning how to perfect this one. But I would definitely recommend buying this lens. If you came here to the comments section for someone to convince you to buy this lens, Im telling you.. DO IT!
