The Sigma Corporation announced the new generation of high image quality compact cameras â€œSIGMA dpâ€ that incorporates a newly developed Foveon X3 direct image sensor (generation name: â€œQuattroâ€).
The Foveon direct image sensor is similar to traditional color film in that its multiple layers capture all of the information that visible light transmits.
Details at Sigma Website.
Following the tradition of their Sigma DP Merill series, the Sigma DP Quattro will come in 3 variants named DP1, DP2 and DP3 – one for each focal length as this is a fixed focal length compact camera.
I’m not technical enough a person to elaborate on the technology of the Foveon sensor but basically it’s a CMOS sensor that picks up details differently from the usual camera that users Bayer sensor (regardless full frame of APS-C).
More details of the technology at Sigma Website.
Judging from the opinions by my friends who are fans of the Sigma DP Merrill, the Sensor of this DP Quattro is different from the previous Foveon sensor as it uses Lab color space with dimension L for lightness and a and b for the color-opponent dimensions.
Ahhh the beauty of imaging technology.
