Digitally optimized circular fisheye auto-focus lens This circular fisheye lens is used to produce circular images with an angle of view of 180° when attached to a full-frame digital or35mm film SLR camera. This auto focus lens is equipped with a new multi-layer coating technology that reduces both flare and ghosting. This lens can be used for the scientific applications. Flare and Ghosting The new multi layer lens coating and lens design reduce flare and ghost, which is a common problem with digital cameras, and also creates an optimum color balance. This large aperture standard zoom lens provides superior performance both for Digital SLR Cameras and 35mm Film SLR Cameras. Equipped with auto-focus system This unique lens is used to produce circular images with an angle of view of 180° and also incorporates auto focus system to get accurate focusing that might be difficult through finder due to extremely large depth of field. Note: It is not possible to produce circular images, if it is attached to SLR cameras other than 35mm full frame size. It is an ideal lens for scientific applications. This lens can be used for the scientific applications such as the solid angle measurements of cloud distribution over the sky, the vegetation distribution of the forest, etc., due to the quantifiable angle/area relationship it produces.
