Sigma Introduces SD1 Weather-Resistant DSLR

Sigma Introduces SD1 Weather-Resistant DSLR

Sigma is a well-known name in the camera industry, particularly the high-end camera industry. And nothing says high-end quite like 46 megapixels. Though, the effective output of the SD1's 46 megapixels is really just 15.3MP (the math goes something like this: 4800 x 3200 x 3), due to a rare 24x16mm APS-C X3 direct image sensor. Sigma claims that this offers more megapixels than any other camera in the market, and while true, you won't get an image with a pixel size any larger than you would from any other 15.3MP camera.

Still, the hardware is impressive. There's a TRUE (Three-layer Responsive Ultimate Engine) II image processing engine, magnesium alloy casing, weather-resistance, and the ability to be called the company's flagship DSLR. They also introduced a few new lenses to go alongside of it, not to mention it having a 3" LCD, CF card support, compatibly with over 40 Sigma lenses, etc. No price is given quite yet, but we're certain it will be lofty. Knowing Sigma's reputation, anyway.

The weather-resistant feature is for convenient outdoor use. The size remains compact.

Sigma also announced the new Electronic Flash EF-610 DG ST, which is designed to work with the latest TTL auto exposure systems of all popular digital and film SLR cameras. Also announced was the new Electronic Flash EF-610 DG SUPER, offering illumination that covers a focal length from 24mm to 105mm.

Here is a closer look at Sigma's new products announced at Photokina:

Sigma SD1

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 24x16mm APS-C X3 direct image sensor and dual "TRUE (Three-layer Responsive Ultimate Engine) II" image processing engines. The direct image sensor featured in the 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.

The unique image processing algorithm of the dual TRUE II image processing engine provides high resolution power and reproduces high definition images with richly graduated tones. The SD1 adopts the TYPE 1 CF Card, and is compatible with the UDMA enabling fast processing of large amounts of data. The autofocus system features an 11 point shifted twin cross type sensor, which improves AF accuracy. The SD1 features a 3.0 inch TFT color monitor. This 460,000 pixel resolution LDC 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 fisheye. The Sigma SD1 is scheduled to be available for shipment in February 2011.

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.
