4.5mm f/2.8 EX DC HSM Circular Fisheye Lens for Nikon F


Product Description

Offering creative distortion and exaggerated perspectives, the Nikon F-mount 4.5mm f/2.8 EX DC HSM Circular Fisheye from Sigma produces a circular image with an expansive 180° angle of view. Benefitting the unique look of the lens is an advanced optical design that utilizes one SLD glass element to reduce color fringing and chromatic aberrations for improved clarity. A Super Multi Coating has also been applied to suppress lens flare and ghosting for greater contrast and color accuracy. Additionally, the lens also features a Hyper Sonic Motor for quick and accurate autofocus performance for working with subjects as close as 5.3" away.
