Product Description

From the Manufacturer
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 introduced at Photokina 2002 by Sigma Corporation of Japan (2-3-15, Iwado-Minami, Komae-shi, Tokyo, Japan).

Sigma’s advanced Optical Stabilizer (OS) allows you to take great pictures with a long lens, even in low-light conditions. The image on the left was taken without Sigma’s OS; the image on the right was taken with Sigma’s OS.
Sigma’s OS (Optical Stabilizer) system detects camera shake by utilizing two sensors, and then by the movement of an optical stabilizing lens group. It is equipped with two optical stabilizer modes to compensate for image blurring.

Mode 1, determines the camera shake in vertical and horizontal panning and compensates blurring, this mode is effective when shooting static subjects.

Mode 2, detects the vertical camera shake, and overcomes blurring. It is especially effective with 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. This lens features full-time manual focusing and a removable tripod collar. The rear focus system prevents the front of the lens from rotating; a circular polarizing filter can be easily attached and used. This lens is also equipped with 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 112-560mm F6.3-7.8 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.

Product Description:
Sigma EX is an ultra-telephoto zoom lens, which overcomes image blur caused by camera shake. A function that compensates for camera movement employing Sigma’s own technology.Using Sigma’s original OS (Optical Stabilizer) function, two types of sensors inside the lens detect vertical and horizontal movement of the camera. By moving a portion of the optical system to compensate for movement, this function delivers outstanding results in compensating for shaking of the camera.Sigma EX offers two types of camera-shake compensation modes to handle all types of shooting conditions. In Mode 1, the system detects and compensates for vertical and horizontal movement of the camera; ideal for still-image photography. And in Mode 2, the system detects and compensates for vertical movement of the camera; ideal for motor sports and other situations where panning may be desired. And, with two SLD (Special Low Dispersion) glass elements in the front lens group and one in the rear lens group, the lens has excellent correction of chromatic aberration and delivers high-definition performance. Full-time manual focus is also available.This lens is designed for Canon Digital SLRs.For a complete compatibility list please refer to the original manufacturer’s web site.
