Sigma Corporation is pleased to announce the launch of the new, groundbreaking Sigma DP1 compact digital camera using three silicon embedded layers of photo sensors stacked to take advantage of silicon's ability to absorb red, green and blue light at different respective depths. The size of image sensor used in DP1 camera is approximately 10 times larger than those used in an ordinary point and shoot digital camera.
Large size image sensor takes advantage of larger pixels. So far point and shoot digital cameras incorporated small size image sensors, and researches for increasing the number of pixels by keeping the image sensor small is still continuing. However, there are limitations in these researches, because keeping image sensor size small will result poor capture of the light poorly. In this respect, enlarging the image sensor will result in better capturing colour signals.
* The Sigma DP1's image sensor is approximately 8 times larger than 1/1.8inch image sensor, approximately 12 times larger than 1/2.5 ordinary point and shoot camera
RAW Image Recording Format
The direct image sensor featured in the SIGMA DP1 ensures the capture of full and complete colour. This camera incorporates both RAW and JPEG image recording formats enabling photographers to capture the highest possible picture definition and smaller file sizes.
Newly developed unique and powerful 'TRUE' image processing engine
'TRUE' (Three-layer Responsive Ultimate Engine) *1 DSP (Digital Signal Processor) suited for Foveon*2 three silicon embedded layers direct image sensor is newly developed (joint development with Fujitsu Limited*3) and incorporated into DP1 first time.
The unique image processing algorithm developed throughout the development of SD9, SD10 and SD14 cameras is incorporated into “TRUE” and enables high-speed image processing.

Exclusive lens for APS-C size image sensor
The accumulated lens design technology and SD series are used for DP1 development. A 16.6mm F4 lens, with a wide angle field of view equivalent to 28mm on a 35mm film camera, has been specially developed to maximise the image quality in conjunction with the full colour capture image sensor.
Glass mould aspherical lens provide correction for all types of aberrations and capture accurate, full colour image information.
Compact and lightweight body
It has compact dimensions of 113.3mm / 4.5in. (W) × 59.5mm / 2.34in. (H) × 50.3mm / 2.0in. (D) and lightweight of 240g/8.5ounces. Its compact body and lightweight design makes it easy to carry everywhere.
Large 2.5" LCD monitor
The Sigma DP1 camera features a new, large 2.5inch, 230,000-pixel resolution LCD monitor. The LCD monitor displays 100% of the image, allowing the photographer to easily and accurately confirm the image composition.
Hot shoe and external viewfinder
DP1 camera is equipped with a hot-shoe thus allowing the attachment of dedicated external flash and high performance external viewfinder (VF11).
Lens Hood (optional accessory)
For assuring maximum performance from the lens and image sensor, it is equipped with exclusive lens hood
