SigmaSigma DP2X digital camera : The Sigma Corporation announces 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 high speed auto focus. AFE is also used in the Sigma DP1x compact digital camera and Sigma SD15 digital SLR and converts full color data, which the Foveon X3 capture system records, into a digital signal. This enables the Sigma DP2X camera to reproduce high definition and richly colored images. In addition, the new AF algorithm provides high speed auto focus, ensuring convenient shooting.

Sigma DP2X image sensor
The size of the image sensor used in the Sigma DP2x camera is 20.7mm x 13.8mm. The image sensor is approximately seven to twelve times larger than the 1/1.8inch to 1/2.5inch image sensors used in ordinary compact digital cameras. The pixel size of the image sensor is 7.8μm. The large photodiodes deployed at a large pixel pitch capture pure, rich light efficiently and give the Sigma DP2x its high resolution and richly-graduated tones.

14 megapixel Sigma DP2X camera
The Sigma DP2x uses the same 14 megapixel (2,652×1,768×3 layers) direct image sensor as the Sigma SD14, Sigma SD15 and other DP series cameras. Utilizing the special features of silicon, which is penetrated to different depths by different wavelengths of light, this direct image sensor succeeds in full-color capture with the full RGB in a single-pixel location. Since the moire is not generated, use of a low-pass filter is not needed because full information of light and color can be captured with three-dimensional feeling.

Sigma DP2X camera processor
The new Sigma DP2x digital camera 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 incorporated in the Sigma DP2X provides high resolution power and reproduces high definition images with richly graduated tones.

AFE (Analog Front End) converts the color data, which full-color capture systems record, to a digital signal. This enables the Sigma DP2x camera to reproduce high definition and richly colored images. The Sigma 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 the Sigma DP2x. Two high refractive index glasses and two molded glass aspherical lenses provide superior image quality and allow compact construction. The Super Multi Layer Coating reduces flare and ghosting. The new Sigma DP2X combines the SLR-sized image sensor and the large aperture of F2.8 to provide natural shallow depth-of-field and attractive bokeh effect.

Sigma DP2X RAW image files
The Sigma DP2x digital camera 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 data format provides pure data for high-resolution images, and uses lossless compression for more compact, yet uncompromised, data files. The RAW data format of the Sigma DP2x keeps brightness and color data in a 1:1 ratio without relying on interpolation. Each pixel location captures the full color of RGB data, so in RAW, X3F files, brightness and color data can be kept in a 1:1 ratio without relying on interpolation. When the photo is processed in Sigma Photo Pro, it will preserve the balance of the natural data for the best photos with the best image quality.

Sigma DP2X software
The supplied image processing software, "Sigma Photo Pro ", converts RAW data quickly and easily. Incorporation of a new noise reduction algorithm reduces Chroma and Luminance noise when processing X3F files taken at ISO400 or more. The Sigma DP2X software makes it possible to adjust the level of reduction for noise just by moving the slider in the control pallet. This software is compatible with multi core CPU’s, ensuring high speed image processing. The Sigma Photo Pro software also incorporates functions such as Loupe, slideshow, Printing, JPEG conversion and batch white balance settings.

Sigma DP2X body
The new Sigma DP2x body has compact dimensions of 113.3mm/4.5in (W) x 59.5mm/2.3in (H) x 56.1mm/2.2in (D). The lightweight Sigma DP2x camera body makes it easy to carry everywhere. The Sigma DP2x has three metering modes, Evaluative Metering, Center Weighted Average Metering and Spot Metering. It is also possible to select the exposure mode from Program AE, Shutter Priority AE, Aperture Priority AE or Manual. Exposure compensation can be set in 1/3 stop increments from +3.0 to -3.0 stops and an auto bracketing function is also available.

Sigma DP2X features
The Sigma DP2x features the QS (Quick Set) menu, designed to allow users to quickly access and change the most commonly used camera functions. The Sigma DP2X digital camera makes it possible to display the QS menu by simply pressing the QS button. QS menu 1 allows users to change the ISO Setting, White Balance, Flash mode and Metering mode and QS menu 2 gives access to Image Size, Color Mode, Image Quality and Drive Mode.

Sigma DP2X flash and autofocus
The Sigma DP2x is equipped with a pop up (manual) built-in flash. It is possible to use Normal Flash, Red-Eye Reduction Flash and Slow Synchro Mode. It also features flash exposure compensation in 1/3 stops increments. The AF area of the Sigma DP2x is equipped with 9 focusing points. It is possible to select the desired focusing point depending on the shooting situation. Manual Focus is also available on the Sigma DP2X for use when autofocus or focus lock is not desired. It is also possible to magnify the display to ensure precise focusing.

Sigma DP2X video mode
The Sigma DP2X incorporates a movie mode to record videos in QVGA (320x240) resolution. The number of shooting frames per second is 30 frames. The recording capacity is approximately 30 minutes by 1GB memory card. The Sigma DP2x camera is equipped with 7 types of the Color Modes which is adjusted saturation, contrast, etc for each shooting situation. It is possible to select from Portrait, Landscape, Vivid, Standard, Neutral, B&W or Sepia.

Sigma DP2X LCD monitor & Hot Shoe
The new Sigma DP2x camera features a large 2.5 inch TFT color LCD monitor. The LCD monitor displays 100% of the images, allowing the photographer to easily and accurately confirm the image compensation. The Sigma DP2x camera is equipped with a hot shoe, allowing use of the dedicated external flashgun EF-140 DG (optional) as well as Sigma electronic flashguns for SD series such as EF-610 DG SUPER and EF-610 DG ST. This hot shoe is also used to attach high performance view finder VF-21 (optional).

It is possible to attach the dedicated lens hood to the Sigma DP2X to block out extraneous light. The Sigma lens hood also functions as an adapter, designed to accept the 46mm Close-up Lens and 46mm filters. Furthermore, the Power Save Mode lowers the battery consumption. When this mode is enabled, a greater number of pictures can be taken with a single charge of the battery.
