News report Photokina - Sigma is pleased to announce the new Sigma APO 120-300mm F2.8 EX DG OS HSM lens The successor to the Sigma APO 120-300mm F2.8 EX DG HSM, introduced to market in July 2005, this new Sigma 120-300mm 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 pictures throughout the entire zoom range.
The Sigma Corporation is pleased to announce the new Sigma 24-70mm F2.8 EX DG HSM lens. This large aperture standard zoom lens covers focal lengths from 24mm and is housed in compact construction. The latest optical design provides an overall length of 94.7cm /3.7inch. It is ideal for general photography such as snapshots, portraiture and landscapes. The Super Multi Layer Coating reduces flare and ghosting. ELD (Extraordinary Low Dispersion) glass, two SLD (Special Low Dispersion) glass elements and three aspherical lenses provide excellent correction of all types of aberrations. Superior optical performance is ensured throughout the entire zoom range.
Sigma launched today a new Four-Thirds system compatible, compact telephoto zoom lens; Sigma APO 135-400mm F4.5-5.6 DG. This telephoto zoom lens gives the equivalent field of view to our popular 800mm when used on Four-Thirds cameras. The very latest lens coating technology and lens design reduce flare and ghosting, a common problem with digital cameras. This lens uses one aspherical lens and three Special Low Dispersion (SLD) glass elements for excellent correction of various aberrations. The rear focusing system ensures fast focusing speed as well as preventing the front of the lens rotating, making it particularly suitable for use with circular polarizing filters.
Sigma launched a new Four-Thirds system compatible, large aperture ultra-telephoto zoom lens; Sigma APO 300-800mm F5.6 EX DG HSM. This Sigma lens covers the equivalent field of view to 600mm to 1600mm when used on Four-Thirds cameras. By continuously varying the angle of view, the lens takes a lot of the footwork out of picture composition. The very latest lens coating technology and lens design reduce flare and ghosting, a common problem with digital cameras. Two ELD glass elements in the front lens group reduce chromatic aberration to a minimum and also ensure high optimum image quality. The overall length of the lens does not change during focusing and zooming, ensuring convenient handling.
The Sigma Corporation is please to announce the new 18-200mm F3.5-6.3 DC OS lens. This high zoom ratio lens is exclusively designed for digital SLR cameras and is capable of covering a wide range of focal lengths from wide angle to telephoto. It is equipped with Sigma’s own unique technology OS (Optical Stabilizer) function. This function uses two sensors inside the lens to detect vertical and horizontal movement of the camera and works by moving an optical image stabilizing lens group, to effectively compensate for camera shake. It automatically detects movement of the camera and compensates for camera shake when shooting moving subject such as motor sports.
The Sigma Corporation is pleased to announce the launch of the new Sigma APO 50-150mm F2.8 EX DC HSM lens.

The incorporation of the very latest optical technology gives optimum lens performance providing excellent correction for flare, ghosting and all types of aberrations. High image quality is assured throughout the entire zoom range. Four SLD Special Low Dispersion glass elements are used for utmost correction of chromatic aberrations.
We have had the opportunity to meet Michihiro Yamaki, President of Sigma Corporation. During our meeting we were shown the latest lenses Sigma has announced just before the Photokina started. The new 18-125mm F3.5-5.6 DC for Four Thirds mount is exclusively designed for use with digital Single Lens Reflex (SLR) cameras and has a 1: 6.9 zoom ratio. A Special Low Dispersion (SLD) and two aspherical glass elements produce a top quality optical performance throughout the entire zoom range. The new Super Multi Layer lens coating, which is optimized for digital SLR cameras, gives superb colour rendition whilst cutting down flare and ghost.
