Sigma 1.4X EX APO DG Teleconverter - Pentax (Refurbished)
SKU: 24444  

Stock:  Yes

The Sigma 1.4x DG EX APO Tele Converter for Pentax (also known as a tele-extender) will multiply the focal length of the existing lens by 1.4x, and will cut back the amount of light by one f/stop. For example, using a 1.4x teleconverter with a 300 mm lens will effectively increase the focal length to 420mm. A lens set to f/2.8 will now be f/4.

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.
