The SIGMA dp0 Quattro is a revolutionary camera, with its high resolution 3 layered Foveon image sensor and incorporates a high performance 14mm F4 lens (equivalent to a 21mm lens on a 35mm SLR).
The SIGMA dp0 Quattro’s 14mm F4 lens achieves the highest optical performance, and 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 and is perfectly suited to landscape photographers.
With the addition of the “SIGMA dp0 Quattro” to the line-up, photographers can select the most suitable camera based on their photographic needs; 21mm (SIGMA dp0 Quattro), 28mm (SIGMA dp1 Quattro), 45mm (SIGMA dp2 Quattro), 75mm (SIGMA dp3 Quattro) and 90mm (SIGMA dp3 Quattro + dedicated conversion lens 1.2x).
