This is my 55-250mm telephoto zoom lens for my Canon T1i. This lens is probably my second most used lens. I like it a lot because its super versatile. Being that it is a telephoto, it produces those lovely blurred backgrounds that everyone loves. I am extremely surprised at how sharp, and clear this lens is! It captures a bunch of detail and has little to no chromatic aberration, which is a bonus for such an inexpensive lens.
