Sigma To Ship 46MP d-SLR

Ronkonkoma, N.Y. -


said Friday it will ship in early June its new flagship d-SLR - model SD1 - at a $9,700 suggested.

The 46-megapixel d-SLR features Sigma's Foveon 23.5- by-15.7mm APS-C X3 direct image sensor for highly detailed images that are capable of being cropped and enlarged to huge sizes.

The camera body features a splash-proof design and will accept a wide range of Sigma interchangeable lenses.

"The SD1 will carve out a new category in the marketplace by providing high-end photographers with an alternative to very expensive medium-format cameras and digital backs, while offering unrivaled image quality," said Mark Amir-Hamzeh, Sigma America president. "By embracing the SD1, serious photographers will also be able to take advantage of Sigma's extensive lineup of affordable lenses, which are compatible with this new camera. The selections of lenses for medium-format cameras on the market are somewhat limited, so this will be a huge advantage for SD1 users. This is undoubtedly a very special camera, and we're thrilled to share it with the photo community."

Other features include a dual "three-layer responsive ultimate engine (TRUE) II" image processing engines, which improve processing speed, provides high resolution power and produces high-definition images with richly graduated tones. 

The SD1 is also the first Sigma camera to include simultaneous RAW and JPEG recording. RAW files can be selected in full-size, half-size or quarter-size formats for greater storage flexibility. The camera stores to a TYPE 1 Compact Flash Card, and is UDMA-compatible.

The Foveon sensor uses three silicon-embedded layers of photo detectors, stacked vertically to take advantage of silicon's ability to absorb red, green and blue light at different respective depths. This technology is said to reproduce colors more accurately and offers sharper resolution, pixel for pixel, than any conventional image sensor. Since color moiré is not generated, the use of a low-pass filter is not required.

Sigma said the optical format of the Foveon sensor has been upgraded from previous SD cameras, increasing from 1.7x focal length to a 1.5x focal length multiplier.

The SD1 also has improved image processing and noise reduction algorithms, with an ISO sensitivity range from 100 to 6400 - two full stops more sensitivity than the SD15, which has a maximum 1600 ISO.

The autofocus system features an 11-point shifted twin cross type sensor, which improves AF accuracy.

A 3.0-inch, 460,000-pixel TFT color monitor has

a wide viewing angle, making it easy to check focusing and composition.

Sigma's bundles its image processing software, Photo Pro 5.0, with the SD1, providing Loupe, Slideshow, Print, Convert to JPEG file and Batch White Balance settings are also incorporated into this software.
