Designed for APS-C sensor digital SLRs, the Tokina AT-X 107 DX is a full-frame fish-eye lens that gives the photographer a 180-degree field of view with dramatic curvature of field or “fish-eye” effect. With this lens an entire view or vista can be captured, wider than the human eye can see. The AT-X 107 opens an entirely new dimension of photography. It has a newly formulated WR or “Water Repellent" optical coating on the glass.
