Sigma's DP2 logo. Sigma DP2: New specs, release nearing
(Monday, March 2, 2009 - 22:14 EST)

Alongside its new lens announcements for the 2009 Spring Photo Marketing Association tradeshow, Sigma has further detailed its upcoming DP2 digital camera, first described at the Photokina show last September.

The Sigma DP2 is closely related to the company's existing DP1 digital camera, but replaces that model's 28mm-equivalent f/4.0 lens, with a brighter, tighter f/2.8 41mm lens. The image processor has also been upgraded to a Sigma TRUE II ("Three-layer Responsive Ultimate Engine") processor with improved processing speed, operation, and performance. The DP2 also has a somewhat revised rear panel control layout as compared to the Sigma DP1.

Body styling of the DP2 looks nearly unchanged since it was last shown at Photokina, although reflecting the attention that Sigma's putting into fine-tuning every detail, we note that a number of the rear panel's screen-printed icons have been replaced with imprints in the corresponding buttons instead. The slight change gives the Sigma DP2 a noticeably cleaner look than previously.

Newly revealed specifications include the ISO sensitivity, minimum focusing distance, flash range, CIPA battery life, dimensions and weight. The Sigma DP2's ISO sensitivity will range from 50 to 1,600, as compared to 100 - 800 in the original DP1. Focusing will be possible as close as 11 inches (28 centimeters), ever so slightly closer than the 12.2" (30cm) provided by the DP1. Likely thanks to the brighter lens, the Sigma DP2's flash will also offer a greater reach than that of the DP1: 3m versus 2.1m at ISO 200. Battery life to CIPA testing standards remains unchanged, at 250 shots per charge. The Sigma DP2's body is 0.2" (5.8 mm) thicker than that of the DP1, with this figure having been increased by 1.5mm since the previously released specifications. Finally, the newly revealed weight of the Sigma DP2 body-only is 9.1 ounces (260 grams) - noticeably lighter than the 9.7 ounce (278 gram) Sigma DP1.

Original Source Press Release:

Sigma announces the launch of a 14 megapixel high definition digital camera, packing the full spec of a DSLR into the body of a compact camera: SIGMA DP2

The Sigma Corporation (COO: Kazuto Yamaki) is pleased to announce the new Sigma DP2 compact digital camera featuring a 14 megapixel FOVEON X3 direct image sensor (2,652 × 1,768 × 3 layers) as used in the Sigma SD14 digital SLR.

Sigma introduced the DP1 with a direct image sensor as used in the Sigma SD14 digital SLR to the market in March 2008 as a “unique, groundbreaking, compact digital camera with all the power of a digital SLR”. The multi award winning DP1 has established strong support from a wide range of photographers both amateur and professional.

Building on this success, the DP2 is equipped with a 24.2mm F2.8 lens, equivalent to 41mm on a 35mm SLR camera, for increasing creative possibilities and superior image quality, improving handling and performance.

After the launch of DP2 camera, it enable users to continue to enjoy the image quality of the DP1 camera for wide focal length photography and also take advantage of the DP2’s standard focal length.

[Main features]

SLR-sized image sensor
The size of the image sensor used in the DP2 camera is 20.7mm x 13.8mm. It 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 DP1 its high resolution and richly-graduated tones.

Full-color image sensor
The DP2 uses the same 14 megapixel (2652×1768×3 layers)direct image sensor as the SD14 and DP1. 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.

“TRUE II” image processing engine
The DP2 incorporates “TRUE II” which is an improved version of “TRUE” (Three-layer Responsive Ultimate Engine), the world’s first image processing engine suited for the three silicon embedded layer direct image sensor. The unique image-processing algorithm, which has been developed throughout the development of the SD series digital SLR cameras and DP1, is incorporated into “TRUE II”.

24.2mm F2.8 lens designed exclusively for the DP2
The DP2 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. 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. SLR-sized image sensor and the large aperture of F2.8 combination provide natural shallow depth-of-field and attractive bokeh effect.

RAW format recording
The DP2 includes a RAW recording mode for retaining full image capture detail of the utmost quality plus a JPEG recording format for convenience. The RAW data format uses lossless compression for more compact, yet uncompromised, data files. The RAW data format of the DP2 keeps brightness and color data in a 1:1 ratio without relying on interpolation. Each pixel location captures the full color of RGB data which, when processed in Sigma Photo Pro, will preserve the balance of the natural data for the best photos with the best image quality.

Exclusive Sigma Photo Pro Software (Supplied with the DP2)
The DP2 comes complete with SIGMA Photo Pro software, a RAW image developer that converts all RAW data quickly and easily. Adjustments can be made in three separate modes. The X3F Mode stores the original settings of the image at the point of capture. In the Auto Adjustment Mode, the software analyzes and automatically makes adjustments to the RAW data. The Custom Mode allows the photographer to make individual adjustments. The photographer can make changes easily and quickly by simply adjusting the slider controls within the software.

Compact and lightweight body
The DP2 has compact dimensions of 113.3mm/4.5in (W) x 59.5mm/2.3in (H) x 56.1mm/2.2in (D). Its compact body and lightweight design makes it easy to carry everywhere.

Three metering modes and four exposure modes
The DP2 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.

Pop up (manual) built-in flash
The DP2 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.

9 point focusing area
The AF area of DP2 is equipped with 9 focusing points. It is possible to select the desired focusing point depending on the shooting situation.

Manual Focus
Manual Focus is available for use when autofocus or focus lock is not desired. It is also possible to magnify the display to ensure precise focusing.

Movie Mode
It is possible to record movies with QVGA (320x240) size. The number of shooting frames per second is 30 frames. The recording capacity is approximately 30 minutes by 1GB memory card.

Color Mode
The DP2 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.

Large 2.5” TFT Color LCD Monitor
The DP2 camera features 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.

Hot Shoe
The DP2 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-500 DG and EF-530 DG. This hot shoe is also used to attach high performance view finder VF-21 (optional).
*EF-500 DG and EF-530 DG flashgun series can be used in manual mode only.

Dedicated lens hood (HA-21)
It is possible to attach the dedicated lens hood to block out extraneous light. It also functions as an adapter, designed to accept the 46mm Close-up Lens and 46mm filters.
*A hood adapter HA-21 is sold separately
