Excerpt: I bought this lens in hopes of making it an all-in-one lens for most uses when traveling. However, since my Canon T5i has video recording capabilities, my expectation was also to be able to use this lens for video.
Excerpt: This lens does not focus properly in low light. Lost all my confidence in the lens while shooting a birthday in a medium lit restaurant. I had to switch back to my kit lens canon 18-55 mm to make sure I got the shots I needed as the sigma was all over the place focus wise.It performs much better...
Excerpt: When I recived this lens. I was exited about it. All the reviews were great. After taking some test shots I noticed that my images where very soft at most of the range when I shot at wide open. Next day I start shooting at f8 to compare Most my photos were sharp.
Summary: I have the earlier model which is both larger and heavier which looks ridiculously appended to my Nikon body. I bought this with the hope that picture quality would be at least the same, but offer smaller and lighter carrying. I was wrong and I returned the updated model within a few days.
