A fast 30mm prime for Sony APS-C mirrorless bodies, giving a 45mm-equivalent view that suits portraits, street scenes and everyday shooting. The f/1.4 aperture and rounded 9-blade diaphragm deliver shallow depth of field and smooth background blur, while two aspherical elements and a high-refractive index element keep distortion and aberrations in check. A stepping motor gives quiet autofocus, useful for video as well as stills. The kit adds a UV filter, a 64GB card and a bag, so it works out of the box; against Sony's own 35mm f/1.8 OSS it is faster but lacks optical stabilization, and against the Sigma 30mm f/1.4's own reputation it is known as a sharp, affordable fast prime with slightly soft corners wide open.

The Sigma 30mm f/1.4 Contemporary is a prime lens for APS-C Sony E-mount mirrorless cameras. It gives a 45mm equivalent field of view. The f/1.4 aperture allows flexible depth-of-field control and handles low light well.
The optical design uses two aspherical elements and a high-refractive index element to minimize distortion and maintain image clarity. A super multi-layer coating reduces flare and ghosting, keeping contrast and color consistent in backlit conditions. The rounded 9-blade diaphragm helps produce smooth background blur for portraits.
Autofocus is quiet and driven by a stepping motor. The kit also includes a UV protector filter, a 64GB memory card and a camera bag.
