Make sure this fitsby entering your model number. 16-35mm ultra-wide-angle zoom lens with f/2.8 maximum aperture 3 high-precision aspherical lens elements produce superior image quality, Closest focusing distance: 0.92 feet Circular aperture produces natural background blur at wider apertures, Ring-type USM for fast and quiet autofocusing; internal focusing Measures 3.5 inches in diameter and 4.4 inches long; 1-year warranty
While there are Canon wide lenses that offer superior corner performance such as the TS-E lenses, this lens is nice as it offers a flexible focal length range of 16-35mm. This allows you to capture everything in the ultrawide-wide focal length. Thus you are not risk at missing a more close-up opportunity when trying to get in an ultrawide shot. Sharpness wise, it is a compromise most definitely, but it is worth this compromise for the extremely useful zoom range of this lens. Recommended, unless you need edge-to-edge sharpness - where Id recommend a TS-E lens instead.

Ive had this lens for over a year now which was bought from Amazon. It is being used on a full-frame 5D and 5DMkII DSLRs. In this price range and wide angle focal length we can compare it to the Canon 14mm f/2.8 or the Nikor 14-24 f/2.8. Why? If youre looking at this lens, then you should be looking at these other two as well. The Nikkor can be used with a Nikon to Canon adapter from some good companies like 16-9 Adapters. This lens may suffer edge softness and I had to have mine calibrated by Canon within the 1 year warranty period. From f/2.8-f/8, this lens is not sharp when compared to the lenses above. From f/8 and beyond it performs well. Overall Im pleased, but at this price, I would want a little better edge sharpness.

For the review of this lens I used my Canon 5D Mk2 Full Frame. When I bought the lens I also purchased a B+W slim UV filter......at over $100. The lens costs $1500, so this seemed like a deal to safe guard the lens and not pickup any filter caused vignetting. PROS: 1. Lens is light. 2. Cant beat f/2.8 3. My purchase is very sharp....if you get one that isnt, send it back!!! Cons: 1. Lens has some vignetting. For me its not serious, but it is there and it is correctable in Photoshop, Photoshop Elements, ACDSee and Im sure a host of other photo editing applications. NOTE: I have posted several pictures for you to judge how serious the vignetting is. (My four pictures were shot looking down at gray concrete so the vignetting would be obvious) 2. Filter is an 82mm, so your others wont fit, plus they are expensive. 3. On a FF its not a walk around lens....35mm just isnt enough for vacation pictures, however with the 5D2 on RAW at 21.1 Mp, you can do some serious cropping. All in all its a lot of money, but if you have the money and own this camera, you will love this lens. I over use this lens because its so sharp and f/2.8 often means no flash. And when attached to your camera you know the quality of the picture is going to be about as good as it gets for a wide zoom. Update: 20 Nov 2011 I had 4 pictures on this site illustrating the various levels of vignetting; only one remains....guess Amazon or Canon didnt like that....even though the vignetting isnt very serious.
