‘For the new dp series, we rethought and redesigned every aspect of the camera, including the sensor, engine, lens and body,’ said Sigma in a statement.

There are three different focal length versions of the dp Quattro: 19mm; 30mm and 50mm (the latter producing the equivalent of a 75mm lens in 35mm format).

Each lens carries a maximum aperture of f/2.8.

First to arrive will be the dp2 Quattro, featuring an eight-elements-in-six-groups 30mm optic with a nine-blade diaphragm.

Sigma claims that the dp Quattro body offers a ‘balanced shape, layout and weight distribution’.

In terms of overall size, the 30mm version, for example measures 161.4x67x81.6mm.

The Foveon X3 Quattro direct image sensor is designed to enable faster image processing and lower power consumption.

A launch date and price has yet to be decided.
