The “SIGMA dp1 Quattro” incorporates 19mm F2.8
(equivalent to a 28mm lens on a 35mm SLR)
high performance wide angle lens,
which is optimized for the Quattro sensor
to maximize the sensor performance,
not only around the focusing point,
but also other areas in the image.

With the release of “SIGMA dp1 Quattro”, photographers can suit cameras to each photography style;
“SIGMA dp1 Quattro” for wide angle photography and “SIGMA dp2 Quattro” for standard photography.
