Sigma DP1x and DP2s

Sigma DP1x

Expected to hit Canadian dealers’ shelves in May, the Sigma DP1x compact digital camera incorporates a “TRUE II” image processing engine, as  used in the Sigma DP2 and SD15 DSLR.

Two years ago, Sigma introduced a high-end compact digital camera with the concept of “a new compact digital camera featuring the same technology as an SLR.” That was the DP1, and it featured the same large image sensor as Sigma’s DSLR cameras. The DP2 was launched a year ago. The DP1x boasts improved image-processing time and a new AF algorithm, providing high-speed autofocusing. In addition, the user interface has been unified with the DP2 series by changing the Set Up Menu and adopting the QS (Quick Set) button.

The size of the image sensor used in the DP1x is 20.7 x 13.8 mm. That’s considerably larger (7x – 12x) than image sensors used in most compact digital cameras. The DP1x’s 16.6 mm f/4 lens (28 mm equivalent) is built to the same design as the DP1’s. The large-diameter aspherical glass provides low distortion and high contrast images. It also offers superior peripheral brightness. The super multi-layer coating reduces flare and ghosting.

The DP1x includes JPEG recording plus a RAW data (X3F) recording mode.

Sigma DP2s

The new Sigma DP2s compact digital camera is the successor to the DP2, introduced a year ago, and incorporates a new AF algorithm, a Power Save Mode and a new rear design. It features a 14-megapixel Foveon X3 sensor.

The new AF algorithm provides high-speed autofocusing. The Power Save Mode lowers the battery consumption. The new rear design aids quick recognition of the controls. The addition of red markings has been used to enable easier operation of the camera’s controls.

The latest RAW image processing software, Sigma Photo Pro4.0, is supplied with the DP2s, making 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 ISO 400 or higher. It is possible to adjust the level of noise reduction just by moving the slider in the control pallet.With the Mac version, functions such as JPEG conversion and batch white balance settings, which were previously incorporated intoWindows versions, have been added. In addition, the print function and the display speed for the review window and thumbnails have also been improved.

This camera is due to arrive in April.
