10.5mm · f/2.8
The Nikon AF DX Fisheye-Nikkor 10.5mm f/2.8G ED offers a 180° diagonal field-of-view on DX cameras, with excellent build quality and compact size. Optically, it is sharp but shows chromatic aberration in high-contrast scenes, correctable in post. Vignetting is present until f/11, and flare is well-controlled. The lens uses screw-drive AF, which is noisy but fast. It suits DX users wanting creative fisheye effects or those willing to correct distortion in software.
