  • Angle 24.4°- 8.2° (1.7х)

The Sigma AF 100-300mm F4 EX DG HSM APO is a fast telephoto 3x zoom lens equipped with an HSM autofocus drive. It has a constant aperture throughout the entire range of focal lengths. The lens is dedicated for full format digital and film SRL  cameras, but can be used on small-format DSRL cameras as well. The optical scheme of the Sigma AF 100-300 mm f/ 4 EX DG HSM APO has four SLD elements to eliminate all types of chromatic aberrations. The multi-coating reduces flare and halation, and corrects color  rendering.

The HSM autofocus drive provides noiseless and high-speed autofocusing with the possibility of  a full time manual focusing without switching to the manual mode.  The internal system focusing and zooming does not affect the size of the lens, and the front element does not rotate, which makes it possible to use the petal hood and a polarizer. It is resistant to dust. It comes completed with a tripod mount ring, which ensures fast rotation of a camera.

The Sigma AF 100-300 mm f/ 4 EX DG HSM APO is compatible with the Sigma 1.4x EX DG APO (AF) or the Sigma 2x EX DG APO (MF) teleconverters for all bayonet mounts. When coupled with the teleconverters, a range of focal lengths of 140-420/5.6 or 200-600/8 respectively can be achieved.

Nikon low-end models are equipped with a built-in motor. Sony and Pentax bayonet mounts are not equipped with a hyper sonic motor, hence they have no HSM index in the name. Only Nikon and Sony  bayonet mounts have a function of   distance information transmission. The lens with the Pentax bayonet mount  cannot be used on SF autofocus cameras.

As a result, the Sigma AF 100-300 mm f/ 4 EX DG HSM APO  is an inexpensive but high-quality lens, but without a stabilizer.
