PMA Show : Sigma DP1 digital camera
Sigma DP1
DP1 high end point and shoot digital camera equipped with 14 megapixel (2652x1768x3 layers) large size direct image sensor
Featuring a large size direct image sensor as used in the digital SLR camera.
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 color 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 color. 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 maximize the image quality in conjunction with the full color
capture image sensor.
Glass mold aspherical lens provide correction for all types of aberrations and capture accurate, full color 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.
