Wider than ever: Sigma dp0 Quattro’s new lens takes aim at architecture and landscape photographers

A year after Japanese camera and optics manufacturer Sigma launched a trio of unusual cameras whose unique sensor design was topped only by their strikingly different bodies, it returns with a fourth model for the family: the Sigma dp0 Quattro. A new, even wider-angle option than past Quattro cameras, the dp0 Quattro marks a departure from the original formula in one respect, as its 21mm-equivalent (14mm actual) prime doesn't sport an f/2.8 aperture like those of its siblings. Instead, this lens has an f/4.0 maximum aperture.

The new lens includes four FLD and two SLD elements, plus two aspherics -- one of them a wide double-sided aspheric. Together, these allow a 91-degree field of view, and to the best of our knowledge, that's the only difference of note from the earlier models beyond size and weight. As in its siblings, the Sigma dp0 Quattro will also feature the company's radical Foveon Quattro image sensor and True III image processor, as well as a body design that's the reverse of most cameras, with a very wide stance and deeply projecting rear thumbgrip, yet only a slight front handgrip.
