Description
Telephoto
Zoom Lens
300-800mm f/5.6 EX DG HSM
This
lens covers the telephoto range from 300mm to the ultra-telephoto range
up to 800mm. By continuously varying the angle of view from 8.2º
to 3.1º, the lens takes a lot of the footwork out of picture composition.
ELD
(Extraordinary Low Dispersion) glass
This digitally optimised lens covers the ultra-telephoto range up to 800mm
and has a fast maximum aperture. Its new lens coating reduces flare and
ghosting, a common problem with digital cameras and also creates an optimum
colour balance.
ELD
Glass
The lens incorporates two ELD (Extraordinary Low Dispersion) glass elements
for effective compensation of chromatic aberrations and ensure sharp,
quality images with high contrast.
HSM (Hyper Sonic Motor)
The addition of an HSM (Hyper Sonic Motor) makes fast, silent AF function
a reality. The lens is also capable of full-time manual focus.
Internal
Focusing and Internal Zooming
Focusing and zooming do not change the lens' overall length, ensuring
it's easy of use either handheld or on a tripod.
Rear
Filter System
A 46mm filter can be inserted near the rear of the lens, and the included
circular polarizing filter can be used in situ.
Included
Tripod Bush
A heavy duty tripod bush is included as standard for use with tripods
and monopods. Multiple threaded holes allow accurate balancing of lens
and camera body. This is also designed as an easy grip when carrying the
lens.
With optional Sigma Apo Tele Converters
When this lens is used with the 1.4x EX or 2x EX Apo Tele Converters (optional),
it becomes a 420-1120mmF8 MF lens or a 600-1600mm F11 MF lens respectively.
