Sigma 300mm f/2.8 EX DG HSM

Sigma 300mm f/2.8 EX DG HSM


Fast maximum aperture telephoto lens optimized for digital SLR cameras. This telephoto lens has a fast maximum aperture, and also features a new super multi-layer coating, which optimizes the characteristics of digital SLR cameras.

ELD Glass

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.

Multi Layer Coating

The new multi-layer lens coating reduces flare and ghosting, a common problem with digital SLR cameras.

Internal Focusing

The Internal Focus system ensures the overall length of the lens does not change during focusing, ensuring convenient handling and ease of use.

HSM System

The HSM (Hyper Sonic Motor) models provide fast, silent AF function as well as full- time manual focus override.

Rear Filter

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.

Optional EX Teleconverters

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.
