Excerpt: I use this product for weddings, portraits and nature.<br />This lens is very well built. Not too heavy. It's not too wide and not too narrow. It is perfect if you trying to get details like flowers, eye lashes, candles. Also, it works perfectly for the portraits. This is my favorite lens. Very fast. <br />It lacks image stabilization but it is barely noticeable!
Pros: Durable, Easily Interchangeable, Fast / accurate auto-focus, Lightweight, Nice Bokeh, Strong Construction
Excerpt: been wanting to get this lens for a while. it's great for shooting in tight spaces and getting that wider shot w/o distortion on the edges. very helpful in adding new looks/angles to my portrait/fashion shots.
Pros: Consistent Output, Easily Interchangeable, Fast / accurate auto-focus, Nice Bokeh
Summary: I'm very happy with this lens. I considered the less expensive Sigma lens, but in the end went with the Canon. The Sigma is supposed to be very sharp. but that's about all it has going for it. On my Canon 5Dmk 3 I can not see any problems with the sharpness of this lens.The lens seems exceptionally sharp wide open even out into the edges.
