Customer Reviews

The best general purpose lens
For an affordable price, this lens gives you excellent performance for every purpose.
The aperture can be set to 2.8 and the portraits are amazing!
At the same time the zoom (up to 75 mm) is also much better than the regular lens provided in the basic canon kit.
In summary, this is a very recommended lens for beginners who don't want to spend a ton of money and still get marvelous results in any situation.

I love this lens!!!!
I purchased this lens after being greatly disappointed by the Sigma 18-200. I have not been disappointed. The images are sharp and the colors are good. I have taken photos for my business with it and have gotten amazing results. If you are stating out professionally, or are a serious amateur, then this is the lens for you. Fast, good in low lighting and it does not feel cheap!

Low Light Auto Focus not good
I purchased this lens to shoot professional bodybuilding show. There are numerous challenges shooting in these low light conditions with the subjects being very dark. The lens didn't focus sharply in these conditions and I returned it. I did shoot some outdoor photo's with the lens and they looked very good. For the money this is a great lens, but if you are going to use it to shoot weddings or other events that may require you to shoot in low light conditions you might want to look else where. For a good alternative check out the Canon 28mm - 135mm IS, even though it is a f/3.5 - 5.6 with the IS you can take great pictures with it in low light conditions and with the extra zoom and the price at about $230 makes it a great deal.
