Sigma AF 15mm f/2.8D Fisheye Review

---

Introduction

The sigma 15mm, is one of two 35mm full-frame fisheye lenses on the market for the Nikon F mount. The other one being Nikons 16mm fisheye. Both lenses have 180 degrees diagonal view. Fisheye lenses have for years been a favorite lens for skateboard and snowboard photographers.With a fisheye lens you will find yourself dangerously close to the action when you do skateboard and snowboard photography. Since the Fov of a fisheye is so extreme, you have to be really close to your subject to fill the whole frame, something that has caused many injuries both to the photographer as well as their equipment.

Positives

• DOF/IR markings.
• Sharp. This lens is quite sharp even wide open.
• Focus speed.
• Close focus is 15cm, a must on a lens this wide.
• Flare resistant, even when shooting directly into the sun.

Drawbacks

• Price, with the price increase of the DG version of this lens you might as well go for nikons gray market 16mm instead.
• Sigma's EX finish, i don't know why people like this, to me it makes the lens less valuable.
• On a FF body there is allot light-falloff at f/2.8, by f/8 light-falloff is minimal.

Verdict

A solid performer, this is probably the best sigma lens i have used. I`ve never been a huge fan of Sigma`s lenses, but since they usually offer cheaper lenses then the other companies, this is often a starting point for the budget photographer. I find this lens less usable on a DX Dlsr, then on a FF camera like the F5. If you own a DX type Dslr then you will be better of getting a DX fisheye. If what you want is just a super wide-angle lens for a DX camera, i suggest the Tokina fisheye to super wide angle zoom lens (10-17mm) or Nikons 12-24mm, if you`r budget is more limited, i suggest the Sigma 10-20mm.

With the price increase of the DG version of this lens, you will be better of with the Nikon 16mm. With a 50$ price difference, i don't see any reason to get the Sigma version. (price compared to Nikons gray market 16mm)
