This telephoto zoom lens is designed with Canon's Optical Image Stabilizer technology while retaining compactness and lightness, in response to demands of photographers. This high zoom ratio lens is equivalent to a focal length of 88-400mm in the 35mm format (when used on Canon EOS cameras compatible with EF-S lenses), and the image stabilizer effect equivalent to a shutter speed about 4 stops faster than the same size lens without Image Stabilizer. In other words, if the slowest shutter speed you could formerly hold a 250mm lens steadily was 1/250th of a second, with Canon's 4-stop stabilization correction, you could hand-hold at shutter speeds as slow as 1/15th of a second. It also uses a UD-glass lens element to correct chromatic aberration for excellent image quality throughout the zoom range. This new EF-S telephoto lens with great features delivers excellent performance at an affordable price for all photographers.

i picked this up when i got my first Canon DSLR (canon T3) and i loved it. i used it all the time and thought i was the coolest thing around. But then i got a 70-200 f/2.6 and this lens now just sits in the camera bag. The autofocus is loud and slow, however, the image stabilizer works great, even at 250mm. i wish the aperture was bigger, but 1:4-5.6 isn't bad.
Cons: not sharp, slow autofocus, 4.0 minimum aperture
This lens is a good starter zoom lens. However, after discovering prime lenses, I realized that it is not very sharp. Sure, it zooms in a lot, but the images cannot compare to a prime lens for sharpness. Also, it can't really be used easily indoors because of the minimum 4.0 aperture. Outdoors, it does a decent job in good lighting, but again, the pictures are not as sharp as they could be. I really would recommend this only to an amateur who isn't planning to shoot in manual. If you are planning on moving up the ladder as far as equipment, I wouldn't bother. Get a 50 mm, 85 mm, or 100 mm lens instead. Despite the price, it's just not worth it.
I got this lens as part of the kit with my T2i. I used it once in a while until Speed week in Florida. I spent the day shooting the stock cars and using it at all zoom lenghts. The results were great, I could not be happier and the feel of plastic is a non-issue. This lens is a steal for the price.
Used on a T2i and it works like a point and shoot at Lacrosse games. Purchased as package with 18-55 IS II so price was all together with bag. Only addition I need to add is a hood because of late afternoon glare. So far this is a fantastic lens.
