Sigma 300-800mm F5.6 EX DG APO IF HSM AF Zoom Lens is an extreme telephoto
zoom lens that is ideal for nature, outdoor or sports photography. This lens
provides a relatively large constant f/5.6 maximum aperture at all focal
lengths.

elements give full correction of chromatic aberration and provide a high level
of optical performance. The improved DG lens design corrects for various
aberrations. This
lens is specially coated to get the best color balance whilst cutting down
on ghosting caused by reflections from the digital image sensor. It provides the
utmost correction against lateral chromatic aberration, which is a serious
problem for digital SLR cameras.
It is also possible to use this lens with Sigma 1.4x EX and 2x EX APO Tele
Converters to convert this lens into an ultra tele-zoom lens, effectively
