Telephoto Zoom Lens
80-400mm f/4.5-5.6 EX DG OS

Optical Stabilizer (OS) function, developed with Sigma's own technology, compensated for shaking of the camera.

Using Sigma's original OS (Optical Stabilizer) function, two types of sensors inside the lens detect vertical and horizontal movement of the camera. To deal with all kinds of photographic situations, the system has two camera-shake compensation mode:1 which detects and compensates for both vertical and horizontal movement, and 2 which compensates for vertical movement only.

SLD (Special Low Dispersion) glass
This lens has two SLD (Special Low Dispersion) glass elements in the front lens group and one in the rear lens group for correction of chromatic aberration throughout the entire zoom range.

Rear focus and zoom lock switch
The rear focus eliminates the need for the front of the lens to rotate, thus allowing the use of circular polarizing filter.
A zoom lock switch is built in to prevent the lens from extending due to its own weight, and the lens is easier to use.

Optional APO Tele-Converter EX
It is also possible to use this lens with Sigma 1.4x EX and 2x EX APO Tele-Converter to make ultra tele-zoom.
With the optional APO tele-converter 1.4x EX, it works as a manual focus tele-zoom lens from 112mm to 560mm F6.3-8. With APO tele-converter 2.0x EX, it works as a manual focus tele-zoom lens from 160mm to 800mm F9-11.

Ephotizone - June 2006
‘Sigma’s OS system is good at what it does… It compensates for movement in both horizontal and vertical planes on the first setting while the second setting ignores horizontal movement such as panning and compensates for just the vertical movement.’ There were virtually no instances of chromatic aberration recorded at any aperture or focal length and flare was hard to introduce without the supplied hood fitted and virtually impossible once fitted. This is a good sign for the DG coatings, as it was possible with the older, non DG version.’ 'At 2/3rds of the price of it’s competitors, this lens looks to be a good value addition to the kit bag.’
   
Photography Monthly - August 2006
‘…it’s big on features too – sporting Optical Stabilisation to limit the effects of camera shake…’ ‘All the faults that can interfere with the quality of your image are minimal, or virtually non-existent – distortion, chromatic aberration and flare. Resolution is outstanding at the shorter end of the zoom and still reasonable at the long end.’ ‘Impressive results, competitively priced and the features worked well.’
   
Which Digital Camera - August 2006
‘The lens coating almost completely banishes flare. Central resolution is outstanding at the shorter end, especially at wider apertures, the edge hold up well too.’ ‘OS worked well, allowing you to shoot at two or three stops slower than usual when hand-holding.’ ‘A good set of results overall and an effective OS system. At two-thirds the cost of its competitors, definitely worth zooming in for a closer look.
   
Professional Photographer - March 2007
‘The Sigma OS system, which operates in near silence, works well…’ ‘In Mode 1, used with proper handheld technique, a high percentage of test pictures taken at 1/60sec with the lens set to a focal length of 200mm were acceptably sharp. Mode 2 must be set when the camera will be panned and this provided some satisfying pictures.’
