The Sigma dp0 Quattro will be released in late June, says Sigma UK, at the same price as its siblings (£899.99 in the UK, $999 in the US).
The ultra wide-angle dp model features a highly corrected 14mm f/4 lens (equivalent to 21mm on full frame) with extremely low distortion.
In order to achieve the highest optical performance, the lens features 4 FLD (“F” Low Dispersion) glass elements, which have performance equal to fluorite, 2 SLD (Special Low Dispersion) glass elements and 2 aspheric lenses, including a wide double-sided aspheric lens. This reduces chromatic aberration and distortion, characteristics that are often present in super wide angle photography.
It offers sharp rendering performance from the maximum aperture, and the superior telecentric optical design improves image quality throughout the frame and maximizes the sensor’s ability by passing on information about subjects to the sensor.
