Nikon AF DX Fisheye-Nikkor 10.5mm f/2.8G ED

The Nikon AF DX Fisheye-Nikkor 10.5mm F2.8G ED is an ultra wideangle, frame-filling fisheye designed exclusively for use with Nikon’s DX (APS-C) format DSLRs. Its main selling points are a 180-degree field of view (offering an equivalent focal length of 15.75mm), and its small size, making it ideal as a 'carry everywhere' lens, ready to be whipped out when the opportunity for an extreme angle of view presents itself. Perennially popular with still and video photographers using Nikon's APS-C format DSLRs this lens only has one serious limitation: Because it lacks a built-in AF motor it will only achieve AF on high-end DSLRs with motors built in to the bodies. Considering its massive natural depth-of-field and limited range of applications, though, this hardly matters.
