This autofocus fisheye lens is designed for use with digital SLR cameras equipped with APS-C size image sensors. The diagonal field of view of this fisheye lens produces striking images with exaggerated perspective & distortion. The minimum focusing distance of 13.5cm/5.3-inch, & maximum magnification 1:3.3 allows subjects to be as close as 1.8cm/0.7-inch from the lens' front element. This close focusing capability allows close-up photography & also it is possible to make use of large depth of field that covers wide range of subjects. The Integral hood blocks out extraneous light & the Super Multi-Layer Coating minimizes flare & ghosting, creating superior image quality. The HSM (Hyper Sonic Motor) ensures fast & quiet autofocusing & allows full-time manual focus override by rotation of the focus ring. This lens is supplied with a gelatin filter holder at the rear, allowing the use of gelatin filters.
