The Sigma 2x EX APO Tele Converter for Sony A mount (also known as a tele-extender) will multiply the focal length of the existing lens by 2x, and will cut back the amount of light by 2 f/stops. For example, using a 2x teleconverter with a 300 mm lens will effectively increase the focal length to 600 mm. A lens set to f/2.8 will now be f/5.6.

Compatibility for Sony a65, a77

Note:
Sigma APO Tele Converter 1.4x and 2x are dedicated teleconverter lenses. Due to the high optical quality of this teleconverter, this item will only fit and work with a select list of lenses. 
The DG denotes an added coating that achieves the best color balance while cutting down on ghosting caused by reflections from the digital image sensor.
