Sigma 80-400mm f/4.5-5.6 APO EX DG OS

Sigma 80-400mm f/4.5-5.6 APO EX DG OS lens

Full frame sized image

Lenses that create APS-C sized image are designed for digital only. They cannot be used on cameras that have image sensor larger than the APS-C format. These lenses are not suitable for film cameras either.


No Ultrasonic AF

Lenses with ultrasonic focusing mechanism tend to be quiter and faster than traditionally focusing lenses.


No stepping motor AF

Lenses with stepping motor focusing mechanism are better for contrast based focusing, and are quiter and faster than traditionally focusing lenses.


One or more Low Dispersion lens element is used

Low Dispersion lens elements help to reduce chromatic aberration.


Built-in image stabilizer

Image stabilization helps to reduce blur caused by hand shake, especially at high focal length or in low light situations. Image stabilization can give 1 to 3 stop advantage over none stabilized lens, based on the reciprocal rule.


Metal mount

Cheaper lenses are usually equipped with plastic mount, while more expensive, professional lenses have metal mount. In general, metal mounts are more durable, and a good thing to have when lenses are changed a lot. When a camera is used mainly with one lens, the material of the lens mount is not that important.


Internal Focusing

Internally focusing lenses don't change their size while setting focus.


The front lens is fixed

The fixed front lens is not rotating during zoom and/or focusing. This allows the photographer to use petal shaped lens hood. Fixed front lenses also make the use of polarization filters a lot easier.


No drop-in filter support

Drop-in filters are used in those lenses where either the front lens is too large, or the field of view doesn't permit the use of traditional filters at the front of the lens. Usually bright tele and ultra-wide angle lenses support this filter type.

Equipped with our Camera Shake Compensation System, this telephoto zoom lens is ideal for digital and 35 mm SLR cameras. Developed with Sigma's own technology, the OS (Optical Stabilizer) function uses two sensor inside the lens to detect vertical and horzintal movement of the camera. The system has two correction modes to handle all types of shooting conditions. SLD (Special Low Dispersion) glass is used for superior correction of chromatic aberration and excellent image quality. This lens is also capable of full-time manual focus.
