We rather liked the Sigma DP2Sand adored the 70-300mm Macro, so when Sigma announced the SD1, we were even more intrigued. With 46MP, this thing looks like a monster that came from the deep. Sigma also announced some new lenses. Press release is after the jump.
Sigma APO 120-300mm F2.8 EX DG OS HSM
This large aperture zoom lens features Sigma’s OS (Optical Stabilization) function and weather-resistant design throughout for use in harsh conditions. One SLD and two FLD glass elements are used for maximum correction of chromatic aberrations. The super multi-layer lens coating reduces flare and ghosting, and the lens design incorporates an inner focusing and inner zooming system to ensure sharp images throughout the entire zoom range. Improved optical performance provides excellent correction of sagittal coma flare, and ensures ultra-high resolution, comparable to a fixed focal length lens. The OS function offers the use of shutter speeds approximately four stops slower than would otherwise be possible. This system enables hand held tele-photography. Incorporation of HSM (Hyper Sonic Motor) ensures quiet and high speed AF, while allowing full-time manual focus override. The addition of the optional APO TELE CONVERTER produces an ultra telephoto zoom lens with AF.
Sigma APO MACRO 150mm F2.8 EX DG OS HSM
The Sigma APO MACRO 150mm F2.8 EX DG OS HSM is a large aperture medium telephoto macro lens which incorporates Sigma’s original Optical Stabilizer function. The successor to the APO MACRO 150mm F2.8 EX DG HSM, introduced to the market in October 2004, offers the latest optical design technology and weather-resistance throughout for use in harsh conditions. A floating focusing system moves two different lens groups in the optical path to different positions. This system compensates for astigmatic aberration and spherical aberration and provides extremely high optical performance from infinity to 1:1 Macro. Three SLD (Special Low Dispersion) glass elements provide excellent correction of all types of aberrations and the Super Multi-Layer Coating reduces flare and ghosting. This lens has superior peripheral brightness and provides sharp and high contrast images even at the maximum apertures. Equipped with Sigma’s own proprietary OS (Optical Stabilizer) function, this lens offers the use of shutter speeds approximately four stops slower than would otherwise be possible. The HSM (Hyper Sonic Motor) ensures quiet and high speed autofocus as well as full-time manual focus capability. This lens has a rounded nine-blade diaphragm creating a smooth blur to the out-of-focus areas of the image. It is also possible to use this lens with Sigma’s optional APO Tele Converters.
Electronic Flash EF-610 DG SUPER
The EF-610 DG SUPER features a powerful Guide Number of 61/m (200/ft) and is designed to work with the latest TTL auto exposure systems of all popular digital and film SLR cameras. The autozoom function automatically sets the optimum illumination angle in accordance with the lens’ focal length in a range from 24mm to 105mm. When the built-in Wide Panel is used, the flash can cover an angle of 17mm. For bounce flash, the flashgun head can be tilted up by 90 degrees, to the left by 180 degrees, or to the right by 90 degrees. It can also be tilted down by 7 degrees allowing ease of use for close-up photography. Among the advanced features of this flash is a modeling flash function, multi-pulse flash, TTL wireless flash, FP (high speed) flash, rear-curtain Synchro flash and manual flash model, which allows the photographer to set the flash power level by up to eight stops. The Auto Power-Off function automatically shuts off the LCD panel to help save battery power. When the flashgun is fully-charged, a confirmation ‘ready’ light will be emitted.
Sigma Electronic Flash EF-610 DG ST
The Sigma Electronic Flash EF-610 DG ST features a powerful Guide Number of 61 and is designed to work with the latest auto exposure systems of all popular digital and film SLR cameras. It features TTL automatic flash exposure control for easy operation. The autozoom function automatically sets the optimum illumination angle in accordance with the lens’ focal length in a range from 24mm to 105mm. When the built-in Wide Panel is used, the flash can cover the angle of 17mm. For bounce flash, the flashgun head can be tilted up by 90 degrees, to the left by 180 degrees, or to the right by 90 degrees. It can also be tilted down by 7 degrees allowing ease of use for close-up photography. In addition to automatic mode, the flashgun features a manual flash mode, making it possible to set the flash power to full or 1/16. When the flashgun is fully charged, a confirmation ‘ready’ light will be emitted and the flash exposure level can be checked through the camera’s viewfinder. Other features incorporated into this flashgun include the Auto Power-Off function to help save battery power.
The Sigma Corporation is pleased to announce the new SIGMA SD1 Digital SLR Camera, incorporating a 46 megapixel (4,800×3,200×3 layers) 24×16mm APS-C X3 direct image sensor.
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 (4,800×3,200×3 layers) sensor and dual TRUE II processing engines ensure the high resolution images are processed quickly with high definition and a smooth and subtle graduation of color.
The SD1 is SIGMA’s latest digital SLR camera which meets high requirements of professional and enthusiast photographers for all types of photography.

[SIGMA SD1 Product Summary]
46 megapixel 24×16mm APS-C X3 Full-color 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 colors at each and every pixel location, ensuring the capture of full and complete color. 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 color 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, meaning light and color, 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.
The SD1 adopts the TYPE I CF Card. This camera is compatible with the UDMA 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.
The Sigma SD1 adopts a lightweight yet solid magnesium alloy body designed to withstand rough use and shocks in harsh conditions.
Buttons and connections benefit from O-ring sealing connections to prevent dust and water getting inside the camera body.
Large, highly visible 3.0” TFT color LCD Monitor
The SD1 camera features a 3.0 inch TFT color monitor. This 460,000 pixel resolution LCD monitor benefits from a wide viewing angle, making it easy to check focusing and composition.
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 the FLD (“F” Low Dispersion) glass elements, which have the performance equal to fluorite glass, SLD glass, Aspherical lenses, Sigma’s own unique Optical
Stabilizer function, Hyper Sonic Motor and Sigma’s Super Multi Layer Coating. They meet the various and demanding requirements of all types of photographers.
