Top quality wide angle lens, with great use for landscape photography.

This lens has been my go to for landscape photography for several Years and the images has been sharp as a tack .

Great value L glass lens. I got this lens to upgrade from my kit lens for my Canon Rebel T5. Just tested this lens out by taking exhibit hall and cosplay photos at San Diego Comic Con.

This lens auto-focuses very quickly, the build quality is superb and when stopped down, the images are very sharp. Highly recommended!

Covering both full-frame and APS-C sensors, the EF 17-40mm has proved popular with photographers since its launch – and for good reason

Build quality; promises only what it can deliver in style

Limited focal range; no IS

I bought this lens while I was away in my Military training, and coming back home to find me a nice looking lens. The condition was mint, although with some scratches as mentioned. I kept it safe and sound in my bag and used it 2 times without any problem. On the 3rd usage, the zoom did not work.

I own this lens for 3 years. It is simply great on crop. Dust and Rain is not a problem. Light weight make it possible for camera to be on your shoulders all the time in bike tours!

Build like a tank; Great lens for travel; You should try hard to broke it! Lowest weight for L lenses; Cool for APS-C

Distortion on full frame; My copy isn't sharp at corners (not a problem on crop

a good lens at a bargain price, but if you want the best IQ you need zeiss prime lenses

cheap; light and good image quality

corners can be really bad at f4

Have had lens for a few years now. At one time also had the 16-35 F/2.8, but honestly ended up using this lens more because it is so much more portable (smaller, lighter). While the new 16-35 v2 is sharper in the corners, it is double the price.
