Sigma 10mm F2.8 Nikon - Description:
The Sigma 10mm autofocus fisheye lens is designed for use with digital SLR cameras equipped with APS-C size image sensors. The Nikon version produces a diagonal angle of view of 180°. The diagonal field of view of 10mm fisheye lens produces striking images with exaggerated perspective and distortion. The minimum focusing distance of 13.5cm/5.3inch, and maximum magnification 1:3.3 in the 10mm lens allows subjects to be as close as 1.8cm/0.7inch from the lens’ front element. This close focusing capability allows close-up photography and 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 and the Super Multi-Layer Coating minimizes flare and ghosting, creating superior image quality. The HSM (Hyper Sonic Motor) in 10mm fisheye lens ensures fast and quiet autofocusing and allows full-time manual focus override by rotation of the focus ring. The 10mm fisheye lens by sigma is supplied with a gelatin filter holder at the rear, allowing the use of gelatin filters.
