Sigma's DP2s digital camera. Photo provided by Sigma Corp. Sigma DP2s: Faster AF for the 41mm Foveon compact
(Sunday, February 21, 2010 - 03:24 EST)

Sigma has today unveiled its new DP2s digital camera, a relatively minor update to the existing DP2 model which launched in September 2008.

Like its predecessor, the Sigma DP2s is based aorund a near-APS-C sized Foveon image sensor, which yields a final image size of 4.7 megapixels. The DP2s' 41mm-equivalent lens has a maximum aperture of f/2.8.

Changes since the original DP2 are largely restricted to firmware and software, with the sole notable hardware change in the Sigma DP2s being the imprinting of icons directly into several of the buttons, and a change of color from blue to red for the playback-mode screen printed icons adjacent to some controls. Firmware changes in the DP2s include updated AF algorithms, and a new power save mode. The product bundle also contains an updated version of Sigma's imaging application, Photo Pro 4.0.

Pricing and availability for the Sigma DP2s have not been announced at this time. For more details, read our Sigma DP2s preview.

Original Source Press Release:

SIGMA DP2s announced

The Sigma Corporation is pleased to announce the new Sigma DP2s compact digital camera featuring a 14 megapixel FOVEON X3® direct image sensor (2,652× 1,768× 3 layers).

The Sigma DP2s is the successor to the DP2 which was introduced to market in April 2009 and incorporates a new AF algorithm, a Power Save Mode and a new rear design. The new AF algorithm provides high speed auto focusing, ensuring convenient shooting. 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. The new rear design aids quick recognition of the controls. The addition of red markings has been used to enable easier operation of the cameras controls.

The latest RAW image processing software, "SIGMA Photo Pro4.0", is supplied with the DP2s and makes processing RAW images quick and easy. Version 4.0 has a superior image processing algorithm and improved compatibility with multi core CPU’s. It provides better image processing speed and improved image quality. Incorporation of a new noise reduction algorithm reduces Chroma and Luminance noise when processing X3F files taken at ISO400 or more. It is possible to adjust the level of reduction for noise just by moving the slider in the control pallet. With the Macintosh version, functions such as JPEG conversion and batch white balance settings, which were previously incorporated into Windows versions, have been added. In addition, the print function and the display speed for the review window and thumbnails have also been improved.

Many dedicated accessories such as the VIEW FINDER VF-21, HOOD ADAPTER HA-21 and ELECTRONIC FLASH EF-140 DG are available for the DP2s.
