The EF-S 17-55mm f/2.8 IS lens is one of the best general purpose, if not the best general purpose lenses on the market with a Canon EF-S mount. It is designed to meet consumer demand for a fast, high quality lens made specifically for those who use 1.6x field of view crop factor digital SLRs. This lens is not suitable for full frame digital bodies. The focal length range of this lens is popular and versatile.
It has an exceptional build quality and near perfect optics. In fact, the UD elements used in this lens are identical to those used in sought after “L series” lenses. An innovative lens coating process helps the glass of the lens reduce flare as well. A Mirco UltraSonic Motor is used to provide superior autofocus (a full time manual mode is available as well).
Moreover, Canon includes a three stop image stabilization system on this lens, making it even more effective in low light conditions than the f/2.8 maximum aperture allows. This lens is recommended for the EF-S mount body user (Canon 30D, 40D, 50D, Digital Rebel) who requires the absolute best in image quality, flare reduction, and general purpose versatility.

What Users Like About This Lens
By far, the best part of the 17-55mm f/2.8 is the Canon UD element. This optical feature makes images shine with crystal clear sharpness and high contrast from frame to frame of every image. Some professionals exclaim that they cannot tell the difference between images taken with “L series” zoom lenses and the EF-S 17-55mm. This is an amazing observation considering that this is a lens designed for amateur photographers. By far, this lens is the best general purpose lens that one could own for use with a 1.6x field of view crop factor digital SLR.
What Users Don’t Like About This Lens
Dust tends to become attracted to the glass elements in the lens as it is not as well sealed as more expensive “L series” lenses are. Additionally, build quality complaints are frequent. While the lens is sturdy, some users feel that for the price it could be more substantial. The only other real complaint is that the lens only works with cropped image sensor camera bodies. Those with full frame bodies are disappointed that they are missing out on a near perfect general purpose lens.
