AF-S Fisheye NIKKOR 8-15mm f/3.5-4.5E ED – Circular Fisheye for Photographers and Content Creators
Nikon’s first fisheye zoom gives photographers and filmmakers an FX-format lens with the look and feel of a circular fisheye and the versatility of a full-frame fisheye, all in one lens. The new lens design provides a creative circular 180-degree vertical / horizontal angle of view on full frame cameras, and zooms to a non-circular fisheye view (180-degree diagonal angle of view) on the long end of the focal range. The lens can also be used on DX-format cameras for a distinctive point-of-view and extreme wide-angle applications. When looking to push creative boundaries, the intriguing perspective from a fisheye lens should be considered to provide a distinct look to your photos and videos, such as a dramatic emphasis on a subject or an extremely wide interior point of view.
The AF-S Fisheye NIKKOR 8-15mm f/3.5-4.5E ED is also the latest in Nikon’s Gold Ring Series of premier lenses and features a next-generation design for high-resolution Nikon DSLR cameras. Made for advanced photographers and creators, this durable lens is constructed of lightweight magnesium alloy, and employs internal focusing (IF) to retain its compact size, even while focusing. It is also Nikon’s latest lens to use an electromagnetic diaphragm for consistent exposure during high speed shooting, or smooth exposure control while capturing video.
The optical formula of the Fisheye NIKKOR 8-15mm consists of three ED elements to reduce chromatic aberration, while two aspherical lens elements minimize coma even at the widest aperture, and enable a more compact lens size. Additionally, the front lens element is coated with Nikon's non-stick Fluorine coat to help resist dirt, fingerprints and smudges, while Nikon’s exclusive Nano Crystal Coat helps reduce ghost and flare.

Review
Lens is very sharp in the center across its zoom-range. The crops at 60% off-center are still very good at 8mm focal length but become a bit softer when the lens is zoomed in. 90% off-center the images suffer from some very visible astigmatism which becomes more pronounced towards the long end.

Given that the performance is excellent and the zoom enables two distinct types of fisheye design to be put into one lens, thus creating a very versatile bit of kit, the price tag looks sound. A Highly Recommended optic for the Nikon system.

Review
8mm
Sharpness is very good at 8mm even wide open, getting a little softer as you move through the aperture stops. It becomes particularly soft once you reach f/16, and softer again at f/22. The best results are found between f/5.6 and f/11. Edge sharpness is reasonably good all the way up to f/16 and f/22, where it softens a little.
15mm
At 15mm lens is sharp at wide open, but best between f/5.6 and f/11. At f/16 it’s a little softer, becoming particularly noticeable from f/22 onwards. At the edges, sharpness is good up to f/16, and becomes softer from f/22 onwards.
