Rectilinear Fisheye. The Sigma 10mm f/2.8 EX DC HSMFisheye provides the classic fisheye look with a 167° angle of view and loads of distortion. It offers full rectilinear coverage (fills the image frame) on APS-C crop-frame cameras.
Exaggerated Perspective. The Sigma has a five-inch minimum focusing distance, providing some interesting close-up effects, especially given its huge depth of field. It allows full-time manual focus, but autofocuses quickly and accurately.
