Design and Features
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 with 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.
The lens is equipped with ultrasonic motor, the autofocus should be virtually silent and fast.
