Lenses & Optics

This is the world's first zoom lens with a constant F1.8 aperture for full-frame mirrorless camera systems.

Designed for APS-C-format Sony E-mount mirrorless cameras, the Sigma 23mm f/1.4 DC DN Contemporary lens delivers a natural and versatile 35mm-equivalent field of view—ideal for street, documentary, environmental portraits, and general everyday shooting. This compact wide-angle prime combines excellent optical performance with a bright f/1.4 aperture, making it a powerful creative tool for both stills and video.

Harness the power of this versatile and portable F2.8 optic with an extended 28-105mm focal range – a standard zoom that goes well beyond the standard.
