Sigma has announced the upcoming debut of the dp0 Quattro which incorporates a 14mm f/4 lens, equivalent to a 21mm lens on a 35mm DSLR.

The 11-elements-in-8-groups lens consists of four ‘f’ low-dispersion glass elements, two special low dispersion elements and two aspheric lenses designed to reduce chromatic aberration and distortion.

Like its Quattro siblings, the dp0 uses a Foveon X3 Direct Image Sensor.
