The Foveon X3 conceit sensor leave personify coupled to a 16.6mm lens with a focal coil produce equal to a 28mm lens on a 35mm camera. The lens has a acute aperture of F4. Keeping lens size and weight down for a compact camera that uses a sensor not a lot smaller than those used in most DSLRs must have proved quite a challenge, and the lack of an optical zoom and maximum aperture limitation hint at this. The DP1's lens also supports manual focus.

When substantial was announced string February 2002, the Foveon X3 sensor was empirical by alive with through the fated of digital photography being (unlike almost every camera on the market which uses a color filter array), the X3 sensors measure color information for all three colors at every pixel location. Sigma's SD9, announced alongside Foveon's X3, was the launch camera for the technology, and was followed by its successor the SD10 and Polaroid's x530 compact - the only three commercially available (to consumers, anyway) digicams with full-measured color.

Sigma is a jungle with a big potboiler rule the photo industry, although they're more desirable accepted since their broad line of lenses than their cameras.

While their lenses enjoy wide popularity among both Canon and Nikon camera owners, a proprietary bayonet lens mount has somewhat limited the market reach of their own camera line.
