Great Lense 4 Full-frame ... Need wider for Crop Camera (40d)
I am not a pro, just a starting event photographer. However, for a year now I have been shopping around for photo equipment: online, in NYC stores, trying out friend's equipmnet, reading reviews, etc. This is a great lens, really sharp, + the 2.8 (which gives great flexibility at low light). However, I have been using it with the Canon 40D (1.6x crop camera); after the first gig I realized that it is not wide enouth. If you a starting up with a crop body and are planning a timely purchase of a full-frame, you will not go wrong with this lens. If not, I would recomend looking into the EF-S 10-22mm. Good luck!!!

Canon EF 16-35mm f/2.8L II USM Ultra Wide Angle Zoom Lens review
I am a hobbiest with a 30D.

This is my first 'L' series lens. I stressed over getting the EF-S 10mm-22mm and the f4 versions both of which are half the price of this lens. I went over the reviews here and at FMreviews. Next, I thought about where I would be using this lens. I tend to shoot in lower light situations and I really wanted to see what this 'L' series lens was all about. I also thought about the future and my plan to eventually go to a full frame camera. I didn't want to have to buy another wide angle lens so this is actually a better idea to have one great lens for both bodies. I wish the included hood was a bit wider as it doesn't help with a bright sun overhead. Other than that I'm very happy with my new lens and will look forward to seeing the world larger than before.

Worth the price over the 17-40mm f/4
I have both the 16-35MM II and the 17-40mm. At the end of the day the images produced by both lenses are sharp. The main difference is the speed. f/2.8 v f/4. When daylight turns to dusk and you're still shooting (ambient light) the option to open up the lens makes it worth it.

Sure its twice the price but the ability to gather more light to get those shots makes it worth it.
