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 canon 17 40mm 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.

About half the price of the 16-35 f/2.8 lens, this L-series lens has an entirely new optical design with three Aspherical elements and a Super UD-glass element. The combination provides superb contrast and sharpness, even at the widest settings. It’s ideal for both film and digital SLRs, and features the same weather-resistant design, rear gel filter holder, and high-speed Ultrasonic Motor as the EF 16-35mm lens.
Customer Digital SLR Lens Reviews
Definitely worth it.
I own a lot of L series lenses from Canon and love this 40mm lens. I used it for a year on my 40D and was pleased, not extatic. Upon upgrading to the 5Dm2 I became extatic. The quality is great on a crop factor but when you compare it to the full frame, you will notice the difference. I also own the 16-35 f/2.8 and if you can afford it, that is the better lens to go with it. The price does correspond to the quality. Overall, I think that anyone buying this lens will be very happy, full framers more so than crop factor types.
VERY VERY pleased… WOW
I’ll just let the photo’s I took do the talking, I took some of my Fender Stratocaster (see most recent photo’s)… The lense is amazing, my company is doing product shots now and I bought this lens so conquer the troubles that it might bring… With very little setup I got some tremendous shots… Amazing and the price it fantastic… If you are thinking about it, it’s a no brainer… My shots were shot with a Rebel XTI.. and these people sent this item fast… You will be very happy with this lens PERIOD!!! Have no fear, click the buy button…
