Description
Telephoto
Lens
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.
