Excerpt: Hey All Always I used to go with my Great Combo 5dm3 with 70-200 ii which is always giving me the "WOW" pictures. But for long time I was not happy with wide angle focal length with 24-105/24-70 2.8 ii/16-35 2.8 Then later I bought this lens after seeing the paper configuration and it blows me away...
Excerpt: Bought to replace the EF-S 10-22mm I used on the 7D before switching to 5D3. It's the equivalent focal length but opens to 2.8 (great for a lot of light) and is L build quality (=survived a drop on concrete with minor repair).
Pros: Consistent Output, Durable, Easily Interchangeable, Fast / accurate auto-focus, Nice Bokeh, Rugged, Strong Construction
Excerpt: Suprisingly low distortion and chroma shifts for such a wide lens. Great for astro photography. It's a bit on the large size but that can be expected, fast af, profiles available with adobe and its quite sharp for something that is so wide.
Summary: I shoot both video and photo and i constantly need a 2.8 wide angle lens...well this lens sure help my needs...and I cannot wait to use thsis on my canon 70d and my canon 6d....i also have canon 24-105 but thats f4.0..i wish i have 24-105 f.2.8 well canon yet to make this one...
Excerpt: I bought this lens a couple of years ago, I do all aerial photography and mount this in belly of aircraft, gives me amazing coverage without having to go so high. It' gives my Zeiss lenses a run for there $. Mounted on my 1ds mark 3, nice job canon
Excerpt: This lens is absolutely awesome. I had to be really be careful to not get too close to the edge of places and had to be aware to keep my feet out of the shot. Every shot was razor sharp using a 6D.
Excerpt: I bought this lens in early 2010, after using it on a commercial shoot. I've always had a soft-spot for the images wide, even ultra-wide lenses can produce. Couple that with a wide maximum aperture and interesting focal range and you have something very special indeed.
Pros: Consistent Output, Durable, Fast / accurate auto-focus, Strong Construction
