Sigma announces DP2x large sensor compact

By dpreview staff on Feb 8, 2011 at 16:57 GMT

CP+ 2011: Sigma has announced the DP2x digital compact camera, a revised version of its DP2 large-sensor compact camera that captures three-color information at 4.7M positions (14M total data points). It features new AF algorithm for faster auto focus, first seen in the DP1x. Other features remain the same including a 2.5" LCD, True II processing engine, and P/A/S/M shooting modes.

Sigma DP2x
Compact digital camera with an APS-C size, 14MP image sensor

  • 14 megapixel Foveon X3 Direct Image Sensor
  • TRUE II Image Processing Engine
  • 24.2mm F2.8 lens designed exclusively for the DP2 series
  • Improved autofocus speed
  • AFE (Analogue Front End) for faster image capture

The Sigma Corporation is pleased to announce the new Sigma DP2x compact digital camera featuring a 14 megapixel FOVEON X3® direct image sensor (2,652× 1,768× 3 layers).

The new Sigma DP2x is the latest DP2 series model and incorporates AFE (Analog Front End) and faster autofocus.  AFE is also used in the DP1x compact digital camera and SD15 digital SLR and converts full color data, which the FOVEON X3® capture system records, into a digital signal. This enables the camera to reproduce high definition and richly colored images. In addition, the new AF algorithm provides high speed autofocus, ensuring convenient shooting.

SLR-sized image sensor
The size of the image sensor used in the DP2x camera is 20.7mm x 13.8mm. It is approximately seven to twelve times larger than sensors used in ordinary compact digital cameras. The large photodiodes deployed capture light efficiently and give the DP2x its high resolution and richly-graduated tones.

Full-colour image sensor
Utilising the special features of silicon, which is penetrated to different depths by different wavelengths of light, this 14 megapixel direct image sensor succeeds in full-colour capture with the full RGB in a single-pixel location.

TRUE II image processing engine
The DP2x incorporates the “TRUE (Three-layer Responsive Ultimate Engine) II” image processing engine which improves the processing speed and overall image quality. The unique image-processing algorithm provides high resolution and reproduces high definition images with richly graduated tones.

AFE (Analogue Front End)
AFE (Analogue Front End) converts the colour data, which full-colour capture systems record, to a digital signal. This enables the camera to reproduce high definition and richly coloured images.

24.2mm F2.8 lens
The DP2x is equipped with a 24.2mm F2.8 large aperture lens, equivalent to 41mm on a 35mm SLR camera, which has been designed exclusively for DP2 series. Two high refractive index elements and two molded glass aspherical lenses provide superior image quality and allow its compact construction.

RAW format recording
The DP2x includes JPEG recording format for convenience plus a RAW data (X3F) recording mode for retaining full image capture detail of the utmost quality. The RAW images can be processed in the supplied Sigma PhotoPro software.

Please correct. APS-C Sensors are bigger.
