Lens Description

The Sigma A 105mm F/1.4 DG HSM is a short telephoto prime designed for cameras with a Full-Frame sensor. This ultra-bright prime has a 105mm focal-length. The body of this lens is weatherproof against adverse weather such as rain and snow. It has sealing to prevent entry of water and dust.

This prime can focus down to 100cm from the imaging plane which gives it a maximum magnification of 0.12X. The lens supports autofocus and features a switch to disengage AF for focusing manually. A Super-Sonic motor inside the lens delivers very fast and relatively quiet AF.

This version has a Sigma S lens mount. Follow this link for all current compatible digital cameras: Sigma S mount cameras. Sigma also made this lens available for Canon EF, Nikon F, Sony E mounts.
