Photokina 2002: In addition to the huge interest surrounding the SD-9 Digital SLR Sigma has also introduced three new big zoom lenses at the Photokina show. These are the APO 80 - 400 mm F4.5 - 5.6 ES OS, APO 120 - 300 mm F2.8 EX IF HSM and the APO 300 - 800 mm F5.6 EX IF HSM. The last of which would provide a huge 1360 mm when mounted on the SD-9! The APO 80 - 400 mm is the first Sigma lens to feature image stabilisation.

Sigma APO 80 - 400 mm F4.5 - 5.6 ES OS

Press release:

An ultra-telephoto zoom lens, which overcomes image blur caused by camera shake

Sigma APO 80-400mm F4.5-5.6 EX OS is one of several new products to be introduced at Photokina 2002 by Sigma Corporation of Japan (2-3-15, Iwado-Minami, Komae-shi, Tokyo, Japan).

Sigma's OS (OPTICAL STABILIZER) system detects camera shake by utilizing two sensors, and then the movement of an optical stabilizing lens group successfully compensates image blur. It is equipped with two optical stabilizer modes to compensate image blurring.

Mode 1, determines the camera shake in vertical and horizontal panning and compensates blurring, this mode is effective when shooting static images.
Mode 2, detects the vertical camera shake, and overcomes blurring. It is especially effective on moving subjects such as motor sports etc.

Two Special Low Dispersion (SLD) glass elements in the front lens group and one in the rear group offer effective control of color aberration. The lens features full-time manual focusing and a removable tripod collar. The rear focus system prevents the front of the lens rotating; a circular polarizing filter can be easily attached and used. This lens is also equipped with a Zoom Lock Switch that eliminates "Zoom Creep". When this lens is used with the 1.4x EX or 2x EX Apo Tele Converters (optional), it becomes a 112-560mmF6.3-7.8 MF telephoto lens or a 160-800mm F9-11 MF ultra-telephoto lens respectively. The lens materials used in this new lens are lead and arsenic free ecological glass.

Sigma APO 120 - 300 mm F2.8 EX IF HSM

Press Release:

A telephoto zoom lens, which retains a constant fast aperture of F2.8 at all
focal lengths

Sigma APO 120-300mm F2.8 EX IF HSM is one of several new products to be introduced at Photokina 2002 by Sigma Corporation of Japan (2-3-15, Iwado-Minami, Komae-shi, Tokyo, Japan).

This telephoto zoom lens has a large aperture of F2.8 that is constant throughout the zoom range. The angle of view of the 120-300mm F2.8 varies from 20.4degree to 8.2degree and offers great versatility of composition from a fixed position. Two Special Low Dispersion (SLD) glass elements in the front lens group and two in the rear group offer effective compensation of color aberration. Since focusing and zooming do not change its overall length, this lens offers ease of handling. HSM ensures a quiet, high-speed AF, as well as full-time manual focus (for Sigma, Canon and Nikon mounts). A removable tripod collar is provided with the lens. As the front of the lens does not rotate, circular polarizing filters can easily be used. When this lens is used with the 1.4x EX or 2x EX Apo Tele Converters (optional), it becomes a 168-420mmF4 AF telephoto lens or a 240-600mm F5.6 AF ultra-telephoto lens respectively. The lens materials used in this new lens are lead and arsenic free ecological glass.

Sigma APO 300 - 800 mm F5.6 EX IF HSM

Press Release:

A 300mm telephoto to 800mm ultra-telephoto zoom lens featuring a constant large
aperture through its entire range

The Sigma APO 300-800mm F5.6 EX IF HSM is one of several new products to be introduced at Photokina 2002 by Sigma Corporation of Japan (2-3-15, Iwado-Minami, Komae-shi, Tokyo, Japan). Sigma APO 300-800mm F5.6 EX IF HSM provides a constant F-number from 300mm telephoto to 800mm ultra-telephoto. This super-telephoto zoom lens has a horizontal angle of view of 6.9°at 300mm and 2.6°at 800mm. Its ability to zoom from a fixed position offers unparalleled versatility in composing an image. It incorporates two pieces ELD (Extraordinary Low Dispersion) glass in the front for effective compensation of chromatic aberration. Since focusing and zooming do not change its overall length, this lens offers ease of handling and operation. The HSM ensures a quiet, high-speed AF function as well as full-time manual focusing capability for Sigma, Canon, Nikon mount lenses. A 46mm filter can be inserted near the rear of the lens, and a circular polarizing filter can be used. When this lens is used with the 1.4x EX or 2x EX Apo Tele Converters (optional), it becomes a 420-1120mmF8 MF lens or a 600-1600mm F11 MF lens respectively. The lens materials used in this new lens are lead and arsenic free ecological glass.
