Compact 45mm Prime for L-Mount

The Sigma 45mm f/2.8 DG Contemporary is a full-frame compatible prime built for L-Mount mirrorless bodies. Its optical formula uses eight elements in seven groups to deliver sharp, detailed results across the frame. At 7.6 oz and 2.5 x 1.8 inches, it adds minimal bulk to a compact camera kit.

Suits everyday and travel shooters.

The bright f/2.8 aperture and rounded seven-blade diaphragm produce smooth background separation for portraits and street scenes. Photographers who need wider apertures for low-light sports, longer reach for wildlife, or 1:1 magnification for close-ups will need a different optic.

Fixed 45mm focal length on full-frame

This lens covers the image circle of full-frame L-Mount sensors at a classic normal perspective. The fixed focal length dictates the field of view and working distance, so confirm that 45mm matches the framing you want before buying.
