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
I needed a quality wide angle lens. This definitely fit the range I was looking for. My first impression was very good. The first landscape photos I captured with it were very sharp. I can't wait to do more with it!
Used this lens to take a shot of the vendors (100+) from the balcony of a show. The picture was featured in the club's magazine, and people were able to pick themselves out quite easily. Does need a tripod.
Quick delivery, easy to use, great angle, crisp
Love this lens. I needed a higher quality wide angle lens that the kit EF-S lens that came with my Crop camera as I knew I was going to go FF eventually. The kit was slow to focus and the images were just not that sharp. Once I put the 17-40 L on my cam body I knew I had the right lens. It has great image quality and focuses extremely quickly. The L build quality has stood up to one accidental drop with absolutely no issues aftwards. My only issue is the not great aperture of F4. I knew that going in and expected it, but one more stop would have made this the perfect lens. For the price, you just can not beat it.
This was my first venture into Canon's "L" lenses. It's fantastic. There's a noticeable jump in quality (feel and image) from the other models. Weight is reasonable too. Didn't come with a hood or bag though :-/
I have owned this for 2 years now and I have loved every second of it. It was my first L series lens and was my only lens for a while. You just can't beat the quality at the price point. Focusing is silent and fast, build quality is great. It is a little soft wide open in the corners, but that is expected with an ultra wide lens. It can easily still be used wide open without loss of image quality. The distortion is well controlled and what remains can be corrected easily in LR. I think it has the perfect amount of distortion that can either be used as an advantage or corrected. One of the things that attracted me to the lens was the weight or how light it is. When you hike in the woods every ounce counts. Comparing it to the 16-35 it is significantly lighter. The close focusing distance has made the f/4 max aperture a non issues outdoors with depth of field. The extra stop could be helpful for wedding or indoor shooting. If you are doing outdoor shooting and want ultra wide angle this is a great lens.
I am a Realtor and am using this lens for HDR interior photos. It has far exceeded my expectation.

The 17-40L is often noted for having soft edges/corners at wider apertures, and this is true. However, stop the lens down and performance is stellar. Color and contrast are incredible. I have used the 16-35 II, 14L II and third part options as well... The 17-40L remains my favorite. The 16-35 II offers nothing except for the f/2.8 over the 17-40 at double the cost. Having used multiple copies of each, I find the sharpness better on the 17-40 (and Canon's MTF charts agree), except for maybe extreme corners. The 14L II is a great lens, but 3x the cost and limited in use due to the fixed focal length. The 17-40L is still the best option for Canon users at this time.
I use this lens for shooting abandoned buildings, so I can more get the scope of the place I'm shooting. THe only thing to keep in mind is that this lens is an f4, so there are some speed and low light issues, but if you're using strobes then it's not a problem. Just be mindful of what you are going to use it for.
