Sigma 8mm f/3.5 EX DG Circular Fisheye Lens Nikon Renewed

The Sigma 8mm f/3.5 EX DG Circular Fisheye is a highly specialized autofocus lens designed for Nikon film and digital SLR cameras. Unlike diagonal fisheye lenses that fill the entire frame with a distorted rectangular image, this circular fisheye projects a complete 180-degree circular image within the sensor area, producing the signature round photograph surrounded by black. This makes it a powerful creative tool for photographers, VR content creators, and anyone looking to capture an extraordinary perspective that no other lens type can replicate.

Optically, the lens employs SLD (Special Low Dispersion) glass to correct chromatic aberration and maintain sharpness across the circular image, while a super multi-layer coating minimizes flare and ghosting even in challenging lighting conditions. With a maximum aperture of f/3.5 and a remarkably close minimum focusing distance of just 5.5 inches, the lens offers versatility for both environmental and close-up creative shots with maximum magnification reaching 4.6x. A rear gelatin filter holder accommodates filters since the bulbous front element prevents the use of standard screw-on filters. This renewed unit has been professionally inspected and tested to meet like-new functional and cosmetic standards.
