Fast maximum aperture F2.8 telephoto lens optimised for digital SLR cameras.

Multi layer lens coating minimises flare and ghost.

Two ELD (extraordinary low dispersion) glass elements produce excellent imaging capability.

Accepts both 1.4x and 2.0x EX Teleconverters to produce 420mm F4 and 600mm F5.6 Autofocus ultra telephoto optics.

The Sigma Corporation is pleased to announce the launch of the new 300 F2.8 APO EX DG HSM lens.

A versatile, fast aperture telephoto lens for both digital and film SLR cameras. Two ELD glass elements reduce chromatic aberration to a minimum and also ensure sharp, quality images of high contrast.

The new multi layer lens coating reduces flare and ghosting, which is a common problem with digital SLR cameras. The overall length of the lens does not change during focusing, ensuring convenient handling and ease of use.

The HSM (Hyper Sonic Motor) models provide fast, silent AF function as well as full- time manual focus override. A drop-in 46mm filter holder in the rear part of the lens barrel can be rotated to facilitate the use of filters, including a polarising filter, in situ.

Simply adding an APO teleconverter (optional extra), means that this lens can be used as a 420mm F4 AF ultra-telephoto lens with a 1.4X EX teleconverter, or a 600mm F5.6 AF ultra-telephoto lens with a 2X teleconverter.
