Summary: Excellent lens.Great for using with fireworks and doing Panoramas.I am amazed at the field of vision and how sharp and crisp the photos were. This lens goes with my travelling kit. Looking forward to using on my next trip overseas.

Finally found the wide angle lens I've been looking for!

Summary: I ordered one of this despite that I know Sigma QA problem. This is just a deal I can't pass. I have a Canon 16-35L but at 16mm, the distortion was not acceptable for video. I studied the distortion chart carefully and at 17mm this lens is as good as my 16-35L at 21mm which both have little...
