Sigma 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
Its new lens coating reduces flare and ghost, which is a common problem with digital cameras. It incorporates two ELD (Extraordinary Low Dispersion) glass elements for effective compensation of chromatic aberrations and also ensure sharp, quality images.
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. A 46mm filter can be inserted near the rear of the lens, and a circular polarizing filter can be used in situ.
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.
