Description

The Sigma 15mm f/2.8 EX DG Fisheye is an ultra-wide fisheye prime lens designed for 35mm full-frame and digital full-frame cameras. Its 180° diagonal angle of view produces pronounced fisheye distortion, making it particularly useful for creative perspectives, architecture, interiors, landscapes, and subjects where an exaggerated wide-angle effect is desired.

The optical design consists of seven elements in six groups, with Sigma's EX construction intended for professional-oriented optical performance and durability. The f/2.8 maximum aperture provides useful light-gathering capability for an ultra-wide lens, while the 15cm minimum focusing distance allows subjects to be placed very close to the front of the lens for strong perspective effects.

The lens uses Sigma's multi-layer coating to help reduce flare and ghosting and maintain contrast when shooting in challenging lighting conditions. Its autofocus system provides convenient focusing on compatible Canon EF cameras, while manual focus can be used when precise control over the focusing distance is preferred.

The Sigma 15mm f/2.8 EX DG Fisheye is a distinctive option for photographers looking beyond conventional wide-angle rendering. Its compact size, close-focusing capability, 180° diagonal perspective, and bright f/2.8 aperture make it well suited to creative photography, dramatic landscapes, architecture, interiors, and experimental compositions.
