Excerpt: I have a Nikon 16mm fisheye for FX, a Bower 8mm for FX/DX and this one. This does a great job, like the 16mm. An important accessory for these is Fisheye-Hemi software from Image Trends. This was the primary reason for adding a third fisheye to my collection. The software does a great job of removing excess curving in the image, when desired.
Excerpt: I originally bought this lens for skateboard photography. Fast at 2.8 and really produces great results. You'll also be surprised at the other uses... interior shots (getting the entire room), interesting group portraits, I also love taking "selfies" with it because you can get a large group in the pic OR if it's just you, you get a full view of the background.
Excerpt: The lens is excellent fo photographing scenes that have natural curves in them already. For example subway stations in Washington, DC, and any domes. Landscape shots also work well. The autofocus is fast, picture quality good.
Summary: I simply can't say enough about this lens. I'd wanted it for a long time but just could never justify the money. Then I rented it and went on a shoot, and shortly after we started shooting it was pretty much decided I had to buy it. After several days of use in various shooting environments and then taking a good look at the images it was easy to get an understanding of how and where the fisheye distorted the image, which then allowed me, to an extent, to shoot w/ that...
