The Nikon AF-S Fisheye Nikkor 8–15mm f/3.5–4.5E ED Lens is ideal for clicking full-frame photos with a circular field of view. It is to be used with Nikon F-mount cameras. This fisheye lens has 15 optical elements arranged in 13 groups, which include 3 extra-low dispersion elements and 2 aspherical elements. These elements prevent chromatic and spherical aberrations throughout the camera's zoom range. A nanocrystal coating is applied on the lens to reduce ghosting and flare, which are caused under bright light. Also, a fluorine coat is applied on the front and rear lens elements to protect them from dust and moisture. An electromagnetic diaphragm with seven blades offers consistency in exposure control at fast shooting rates and provides a beautiful bokeh effect on images. This Nikon lens has a Silent Wave Motor that automatically focuses on the object without making any noise. You may also switch to manual focus by rotating the dedicated ring on the lens.
