AX | APO | HSM | IF CONV

Sigma’s APO 300-800mm F5.6 EX DG HSM is another unique lens in the line of Sigma offerings. An ultra telephoto as no other camera or lens manufacturer offers the serious photographer! Featuring a constant aperture of F5.6 throughout the entire zoom range, this lens is ideal for photographing wildlife when there is no way of controlling the distance of the animal to the camera. With a simple turn of the zoom ring, the photographer can instantly adjust the composition of the image without moving or disturbing the subject. Similarly, the zoom accommodates sporting photography such as soccer or surfing where the rapidly changing distance of the action requires massive changes in focal length in a matter of seconds. Two SLD (Special Low Dispersion) glass elements provide optimum color correction & sharpness throughout the entire zoom range. At the rear of the lens, a drop in 46mm filter holder is provided so that the photographer can easily add inexpensive color correction or light balancing filters. A perfect lens for surveillance use, its stealth black finish is unobtrusive and easily concealed.

From 300mm telephoto to 800mm ultra-telephoto 
this new lens provides a constant fast maximum aperture 
and is optimized for digital SLR cameras.

This lens covers the telephoto range from 300mm to the ultra-telephoto range up to 800mm. By continuously varying the angle of view from 8.2° to 3.1°, the lens takes a lot of the footwork out of picture composition.

New coating reduces Ghost and Flare

The new multi layer lens coating and lens design reduce flare and ghost, which is a common problem with digital cameras and also creates an optimum color balance.

It also features a drop-in filter

It also features a drop-in 46mm filter holder in the rear part of the lens barrel, which can be rotated to facilitate the use of filters, including a polarizing filter.

Internal Focusing and Internal Zooming

Since focusing and zooming do not change its overall length, this lens is easy to hold and use. In addition, since the front of the lens does not rotate, a circular polarizing filter can be easily attached and use.

It is equipped with ELD (Extraordinary Low Dispersion) glass elements

Two ELD glass elements in the front lens elements reduce chromatic aberration to a minimum and also ensure sharp, quality images of high contrast.

Accepts both 1.4X and 2X APO EX 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.

HSM (Hyper Sonic Motor for Sigma, Canon and Nikon mount lenses)

The HSM models provide silent, high-speed and precise auto-focusing with full time manual focus override.
