Additional information:

The Sigma AF 30 mm f/ 1.4 EX DC HSM  is a fast wide-angle lens for digital APS-C and 4/3 cameras.

On  APS-C cameras the equivalent focal length is 45 mm, on 4/3 – 60 mm.

A maximum aperture ratio of 1.4 coupled with rather wide angle makes it possible to shoot with shallow depth of field and in poor lighting conditions.

The lens has an 8-blade aperture. The bokeh is pleasant.

The Sigma AF 30mm f/1.4 EX DC HSM is rather sharp at f/ 1.4 already. It is very sharp from f/4 onwards.

Two SLD elements effectively correct chromatic aberration, and the aspherical lens, introduced into the scheme, effectively combats distortion.

The  HSM (Hyper Sonic Motor) makes focusing fast and silent.

Vignetting is rather sever at f/1.4 and remains visible up to f/4. From f/4 it is not noticeable.

Focusing is internal. The front lens does not rotate. It is possible to manually adjust sharpness at any time by turning the focusing ring.

Color  rendering is bright and saturated. Contrast of images is high.

The Sigma AF 30mm f/1.4 EX DC HSM is perfect as an all-purpose kit prime lens for digital APS-C and 4/3 cameras. It is fit for most types and genres of photography.

Compatible hood: LH715-01 300

A soft carrying case and a petal hood are included with the lens.

Attention:

Pentax and Sony/Minolta versions are not equipped with a hyper sonic motor.
