The Sigma dp2 Quattro is an advanced compact camera based around Sigma’s Foveon sensor technology. Key features include:

29MP Foveon X3 Quattro Direct CMOS Sensor. The Foveon image sensor captures full-color information vertically rather than horizontally, meaning each pixel has complete color information. What separates this version from previous Foveon sensors is the 1:1:4 pixel layer approach that uses a 20MP on the top layer and 4.9MP on each of the bottom two. While the actual image file size that comes out of the camera is 20MP, the image quality is equivalent to about 39MP.

Improved Performance. The updated TRUE III image processing engine provides faster camera operation, improved autofocus, and less power consumption. Additionally, low-light performance sees improvement, with an ISO sensitivity range of 100-6400 in 1/3 steps.

45mm Equivalent Lens. The integrated 30mm f/2.8 lens is equivalent to 45mm after sensor crop factor, making the dp2 Quattro a great choice for landscapes, portraiture, street, and general-use photography. Its f/2.8 aperture gives you both low-light ability, as well as subject-background isolation with a shallow depth-of-field.

Design. Compared to previous generations (and really any camera made), the dp2 Quattro has a somewhat odd ergonomic design. Despite this, the controls are placed in a way that take advantage of the elongated body, ensuring your hands won’t obscure the screen while shooting. However, this comes at the expense of eliminating it as a “pocket camera.”

Other Notable Features. The 3.0" 920k-dot TFT rear LCD is large and bright for image composition and review. Full 14-bit RAW capture is possible, but do note you’ll have to use Sigma’s free proprietary software to process the files so be forewarned. The camera records images to SDHC / XC memory cards, and uses an updated BP-51 rechargeable battery.
