"Razor sharp fast focus, small enough to carry all the time and now that I take a few special shots on my jobs, this lens always helps to close a sale." bhphotovideo.com
"The thing I love with this, is at 10mm you get the full on 180 degree fisheye experience and at 17mm it's only slighty curved but wide enough to still fit a lot in frame. Build quality is really good. feels solid & expensive, well built with a bit of weight to it." bhphotovideo.com
