Canon EF 17mm to 40mm f/4 Wide-angle rÏom lens

A new and affordable L-series ultra-wide-angle zoom lens that's ideal for both film and digital SLRs. Superior optics are assured by the use of three aspherical lens elements, in addition to a Super UD (Ultra-low Dispersion) glass element. Optical coatings are optimized for use with digital cameras. This lens focuses as close as 11 inches (0.28m), and offers both Canon's full-time manual focus and a powerful ring-type USM for fast and silent AF. It has a constant f/4 maximum aperture, and offers the choice of screw-in 77mm filters or a holder in the rear of the lens for up to three gel filters. Finally, it offers weather-resistant construction similar to other high-end L-series lenses. more

3/5: From: Amazon; Posted: Jul-06-2008; Great on full frame, average on crop bodies; This is a good lens, but it's certainly not great. Along with all other L-series lenses, it's more durable, weather resistant, doesn't rotate the front element. It has a virtually silent focusing motor which is a pleasure to use. The...; read full review | report as inappropriate
