The Bower SLY 358C 8mm f/3.5 Ultra-Wide Fisheye Lens is compatible with Canon APS-C EOS cameras; it features a 180° angle of view that allows the photographer to see his subjects in unique way. This ultra-wide delivers a rounded perspective, well-suited to landscapes and unusual portraiture. It has multi-coated elements and a fixed petal-type lens hood to reduce flare and ghosting. This lens must be used in manual focus and manual exposure modes.
