Brand: Canon
Located in: Lenses For Canon
An 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.

Comments about Canon Canon 17-40mm f/4 L USM EF Wide-Angle Zoom Lens:

I do alot of nature and anything else that catches my eye. It's very versatile with a good range in focal leighth for getting wide landscapes or close ups of things near you. The focusing distance is great. Feels solid and durable in hand with very accurate color contrast/sharp images. It squeaked once during focusing which was weird but never happened agin. Great lense.
