Excerpt: I always wanted to try out a fisheye so I rented the Sigma lens and I liked it enough that I bought one. It's small, lightweight, auto focusses well and it's sharp enough. You wouldn't likely use this as your every-day walking around lens, but the unique perspective a fisheye gives opens up some interesting creative possibilities. It's fun to make those prototypical bulging pictures of people and things - for about the first hour.
Pros: Consistent Output, Fast / accurate auto-focus, Lightweight, Strong Construction
Excerpt: I like it so far, but you have to love fisheyes and know how to take advantage of them. I found it nice for doing midnight panoramas and stitching them together. Lightroom will also do some corrections to make the pictures rectilinear, but you also have to keep in mind the angle at which you hold the lens is *way* more important than a longer lens. i.e., sometimes you also need to do vertical adjustments in lightroom as well.
Excerpt: I am a professional photographer full time 30yrs and bought this lens for a family wedding to play with and ended up using it for 70% of reception. It was great for the wild shots and gave a different view not normally seen with background lights of different color temp. Easy to work on a crowded dance floor. Used on my 5D mk3 had some barrel effect but make a rather dark party place look massive and bright. Very sharp for the price... I would do it again.
Pros: Consistent Output, Fast / accurate auto-focus, Lightweight
Excerpt: I already use a Canon 17-40 mm lens on Canon 5d III but to go even wider, the Sigma 15 mm was needed. A well made solid lens. Noisy, slow focus but this is not an issue with how the lens is typically used. Images at f8 and f11 are very sharp. Yes lots of distortion but it is a 180 degree view lens on a full frame body. Amazing depth of field particularly at f16 and f22.
Pros: Amazing depth of field, Ultra Wide Angle View
Excerpt: I used to shoot underwater with the Tokina 10-17mm and the Nikon D300, but when I upgraded to the D800, this lens is the way to go. Recently on a month long cave dive trip, this lens performed flawlessly. I was shooting between f.8 and F.5.6, and the shots are incredibly sharp. While I miss the zoom capability of the 10-17mm, I recall I always had it set on max wide anyway. 15mm Sigma is the way to go underwater!
