The Sigma EX 15mm f2.8 Fisheye is a full-frame fisheye lens for Nikon F mount cameras. Surprisingly compact, this lens will mount to any Nikon SLR camera, film or digital: because it has a manual aperture ring, you can use it on any film camera from the F on up, and its electronic contacts make the newest DSLRs happy. Autofocusing requires a camera with an in-body motor, but honestly, it’s a fisheye lens: almost everything’s in focus 90% of the time, anyway. In excellent condition, with front and rear caps.
