Sigma 300mm f/2.8 EX DG HSM SLR Telephoto lens Black

Telephoto Lens, 300mm, f/2.8 EX DG HSM, 2400g 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.

<b>ELD Glass</b>
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.

<b>Multi Layer Coating</b>
The new multi-layer lens coating reduces flare and ghosting, a common problem with digital SLR cameras.

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

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

<b>Rear Filter</b>
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.

<b>Optional EX Teleconverters</b>
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.
