Lens Description

The Sigma 50mm F1.4 EX DG HSM is a normal prime designed for cameras with Four-Thirds (2X) sensors. This ultra-bright prime has a 50mm focal-length. It provides the same field of view as a 100mm lens on a Full-Frame camera.

This prime is capable of focusing down to 45cm from the imaging plane which gives it a maximum magnification of 0.13X. 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 Four-Thirds lens mount. Follow this link to see all current compatible digital cameras: Four-Thirds mount cameras with Four-Thirds (2X) or larger sensor. Sigma also made this lens available for Canon EF, Nikon F, Pentax K, Sony A, Sigma S mounts.
