The Sigma 2× DG EX APO Tele Converter for Pentax will multiply the focal length of the existing lens by 2×, and will cut back the amount of light by one f/stop. For example, using a 2× 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.
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.
Note: Sigma APO Tele Converter 1.4× and 2× 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. Please click here for a compatibility chart of all compatible lenses at Sigma website.
