A full-frame fisheye lens with 180° diagonal angle of view. Unlike other AF (autofocusing) SLR lenses, close auto focusing is possible to a distance of 0.2m, enabling the creation of powerful images using the exaggerated near-far relationship and pan-focus effects characteristic of a fisheye lens. Despite being a fisheye lens, straight lines running through the center remain undistorted. The AF is driven by an AFD (Arc-Form Drive). This lens uses rear drop-in type gelatin filters, up to 3 filters at the same time.
