Sigma | Sigma 56mm f/1.4 DC DN Contemporary Lens

Smooth AF ideal for video shooting

The combination of optical design for video AF and use of the stepping motor enables smooth and quiet autofocus.This lens is also compatible with the Sony E-mount Fast Hybrid AF, achieving precise AF tracking. By using the face recognition or eye AF functions of cameras, focus will continuously be on the face or the eye even if the subject moves during the shoot.

Bayonet mount

High-precision, rugged brass bayonet mount

The brass mount combines high precision with rugged construction. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens.

Mount with dust- and splash-proof construction

The mount features a special sealing to make the lens an excellent choice in a wide variety of conditions.

Dust and Splash Proof
Minimized Flare and Ghosting

Designed to minimize flare and ghosting

From an early stage in the lens design process, flare and ghosting have been measured to establish an optical design resistant to strong incident light sources such as backlighting. SIGMA’s Super Multi-Layer Coating reduces flare and ghosting to help photographers produce sharp and high contrast images even in backlit conditions. The included lens hood can be attached to block out extraneous light, which can have a negative effect on rendering performance.

Rounded diaphragm
