Telephoto Zoom Lens
120-300mm f/2.8 EX DG HSM

A digitally optimised telephoto zoom lens covering ultra-telephoto up to 300mm with a fast maximum aperture of F2.8 at all focal lengths.

This lens represents a revolutionary leap forward in ease of use. This was achieved by transforming a large-aperture 300mm F2.8 lens into a zoom lens that allows you to determine the picture composition you want without having to change your vantage point.

SLD glass and aspherical lenses
It has two SLD (the special low dispersion) glass elements in front group and another element of SLD is being used for rear group for excellent correction of chromatic aberration. The new lens coating reduces flare and ghost, a common problem with digital cameras and also creates an optimum natural colour balance. It prides excellent imaging capability like a prime lens.

Hyper sonic motor
The AF drive for Sigma SA, Canon and Nikon cameras is equipped with a silent, responsive and high speed HSM , which also provides full-time manual focus function.

Sigma Apo Tele Converters (optional)
High-speed focusing is possible when this lens is used with dedicated APO EX tele-converters (1.4x and 2x). By adding an APO tele-converter, which is sold separately, you can use this lens as a 168-420mm F4 AF tele-zoom lens with a 1.4x tele-converter, or as a 240-600mm F5.6 AF ultra-telephoto zoom lens with a 2x tele-converter. It is also possible to use AE (Automatic Exposure) function, even EX Tele-converters are attached to the lens.

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.

Ephotozine - March 2005
‘From the moment you take this lens out of the box you realize the build and feel is excellent.‘ ‘The lens does not change length when zooming or focusing with all adjustments happening internally. This is an excellent feature when using the lens on a beanbag as the focus ring does not turn during autofocus.’ ’The lens is fitted with Sigma’s HSM autofocus system (Hyper-Sonic Motor) and is quiet and responsive in use. Focusing speed is dependent on the camera that it is fitted to, but this lens is no slouch and gave us a pleasing performance. The system can be over-ridden by turning the focus ring to tweak an autofocused setting, or completely disabled (on Canon, Nikon and Sigma mounts) to leave full manual focusing by the movement of a small switch on the left side of the lens, adjacent to the mount.’
   
RPS Journal - June 2007
‘The 120-300mm lens proved to be adaptable, being equally suited to candid portraits in the paddock and shooting bikes on the track. When combined with the 1.4x teleconverter, it gave a useful range of focal lengths and autofocus performance was still impressive. Even wide open at f/2.8, the 120-300mm was sharp across the whole frame, with little deterioration in the corners. Stopping down to f/4, it was even better - on a par with the best prime lenses. Sharpness was still excellent when the lens was combined with the 1.4x converter, and was very good with the 2x converter.’ I
   
Digital Photographer - Issue 58
‘The lens is fitted with Sigma’s HSM autofocus system and is quiet and responsive in use. Focusing speed is dependent on the camera that it is fitted to, but this lens is fast! In our tests, we found the contrast throughout the zoom range to be consistently good and it’s virtually as sharp wide open as it is stopped down two or three apertures. Control of aberrations is excellent, helped no doubt by the inclusion of four SLD elements: two in the front group and two in the rear.’
   
Photography Monthly - September 2007
‘…it is a cracking piece of optical engineering with good wide-open performance that quickly jumps to excellent within a stop of the widest aperture. Distortion is negligible and aberrations are very well controlled.’ ‘The lens is a fast prime with the ability to zoom out - an excellent concept. It does have superb optical performance.’
