Design and Features
The updated version of Sigma 15mm F/2.8 EX Diagonal Fisheye (1999) optimized for use with digital cameras. For general information on fisheye lenses please refer to the article dedicated to Canon EF 15mm F/2.8 Fisheye.
The lens barrel is of moderate weight, made of high-quality plastic. The lens mount is metallic. The lens barrel has a "crinkle" paint finish (refer to the article dedicated to Sigma 85mm F/1.4 EX DG HSM for more information about the finish).
The lens features AF/M focus mode switch.
|AF||Autofocus mode without Full-Time Manual Focus.|
|M||Manual focus mode.|
Due to the prominent convex profile of the front element the lens does not have a filter thread. However, the manufacturer provided a slip-in filter holder for cut gelatin filters at the rear of the lens.
Canon version of the lens is equipped with micromotor, the autofocus should be moderately noisy but fast.
- The autofocus will not be available with Nikon D40, D40X, D60, D3000-D3400, D5000-D5600 SLR cameras.
