The Sigma Corporation is pleased to announce the new Sigma APO 120-300mm F2.8 EX DG OS HSM. The successor to the APO 120-300mm F2.8 EX DG HSM, introduced to market in July 2005, this new lens offers the latest optical design technology.

This large aperture zoom lens features Sigma's OS (Optical Stabilizer) 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 4 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 rounded 9 blade diaphragm creates an attractive blur to the out of focus areas of the image. 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 market in October 2004, offers the latest optical design technology and weather-resistant design 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 4 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 9 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 Sigma Corporation is pleased to announce the launch of the new ELECTRONIC FLASH EF-610 DG SUPER.

The EF-610 DG SUPER features a powerful Guide Number of 61 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 mode, 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.

ELECTRONIC FLASH EF-610 DG ST

The Sigma Corporation is pleased to announce the launch of the new ELECTRONIC FLASH EF-610 DG ST.

The EF-610 DG ST features a powerful Guide Number of 61 and is designed to work with the latest TTL 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 also 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.
