SIGMA 30mm f/1.4 Contemporary DC DN Sony E camera lens

Prime wide-angle for APS-C E-mount

The Sigma 30mm f/1.4 Contemporary DC DN is a fixed focal-length lens built for Sony E-mount APS-C mirrorless cameras. Its bright f/1.4 maximum aperture gathers ample light for low-light shooting and shallow depth of field. The compact design balances high optical performance with an accessible price point. It includes a lens hood and front and rear caps.

Step up from variable-aperture zooms

This prime replaces slower kit zooms that typically stop down to f/3.5 or smaller at longer focal lengths. The constant f/1.4 aperture is worth the switch when you need consistent exposure while composing at 30mm. Two aspherical elements and one high-refractive index element correct distortion and chromatic aberration. Super Multi-Layer Coating suppresses flare and ghosting for cleaner contrast.

Fits compact APS-C kits

The lens mounts directly on Sony E-mount APS-C bodies and Micro Four Thirds cameras via adapter. A stepping motor drives fast, quiet autofocus suitable for stills and video. Nine rounded aperture blades produce smooth background blur at wide apertures. The optical formula covers an APS-C image circle, so it does not illuminate a full-frame sensor.
