Sigma today announced the development of a significant step forward in its DSLR range with the Sigma SD1. Featuring a new, larger (24x16mm) APS-C Foveon sensor with three 15MP layers, producing a total 46MP resolution, the new camera also has a completely redesigned magnesium alloy body which is splashproof.

Other new features include a new 11 point AF system, a new processing engine, (Dual TRUE II) and, for the first time in a Sigma DSLR, the ability to shoot Raw and JPEG simultaneously.



Sigma SD1 ? Press Release

The SIGMA SD1 is Sigma’s flagship digital SLR model, adopting a lightweight yet solid magnesium alloy for its body and O-ring sealing connections to make a weather-resistant design throughout for use in harsh conditions.

The SIGMA SD1 incorporates a 24×16mm APS-C X3 direct image sensor and dual “TRUE (Three-layer Responsive Ultimate Engine) II” image processing engines. The combination of the 46 megapixel sensor and dual TRUE II processing engines ensure the high resolution images are processed quickly with high definition and smooth and subtle graduation of colour. The SD1 is SIGMA’s latest digital SLR camera which meets high requirements of professional and enthusiast photographers for all types of photography.

Product Summary

46 megapixel 24×16mm APS-C X3 Full-colour image sensor

The 46 megapixel (4,800×3,200×3 layers) 24×16mm APS-C X3 direct image sensor featured in the Sigma SD1 captures all primary RGB colours at each and every pixel location, ensuring the capture of full and complete colour. Using 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, it efficiently reproduces colour more accurately, and offers sharper resolution, pixel for pixel, than any conventional image sensor. Since colour moiré is not generated, the use of a low-pass filter is not required, meaning light and colour, generated by the 46 megapixel APS-C X3 direct image sensor, is captured with a three-dimensional feel.

Dual TRUE II image processing engine

The SD1 incorporates a dual “TRUE (Three-layer Responsive Ultimate Engine) II” image processing engine which improves the processing speed and overall quality of the final image. The unique image-processing algorithm provides high resolution power and reproduces high definition images with richly graduated tones.

CF card

The SD1 adopts the TYPE I CF Card. This camera is compatible with UDMA Mode6, enabling fast processing of large amounts of data.

* It is not possible to use Microdrives and TYPE II CF cards.

11 point twin cross sensor

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

Magnesium body

The Sigma SD1 adopts a lightweight yet solid magnesium alloy body designed to withstand rough use and shocks in harsh conditions.

Weather-resistant design

Buttons and connections benefit from O-ring sealings to prevent dust and water getting inside the camera body.

Large, highly visible 3.0″ TFT colour LCD Monitor

The SD1 camera features a 3.0 inch TFT colour monitor. This 460,000 pixel resolution LCD monitor benefits from a wide viewing angle, making it easy to check focusing and composition.

Optional lenses

The SD1 can be used with over 40 Sigma lenses such as ultra-wide, ultra-telephoto, macro and fisheyes which adopt the latest technology such as FLD and SLD glass, Aspherical lenses, Sigma’s unique Optical Stabiliser function, Hyper Sonic Motor and Sigma’s Super Multi Layer Coating. They meet the various and demanding requirements of all types of photographers.
