Nikon 10.5mm f/2.8G ED AF DX Fisheye Nikkor Lens
Nikon's 10.5mm offers the look of a rectangular fisheye without getting too extreme. This lens, however, performs even at close rangesas close as 5.5 inches (1.2 inches from the lens front). And when used for macro shots, the fast f2.8 aperture will leave images with a nice depth of field. A seven blade rounded diaphragm helps prevent further distortion of the out-of-focus elements. Along with the close focusing, this lens also has a 180 degree view. Nikon has also included their Close Range Correction system that helps ensure close subjects are crisp and in focus.
