2x Autofocus Teleconverter for Pentax (4 Element)

  • Category: Autofocus Teleconverters
  • Model Number: SX4DGP

The 2x DGII Teleconverter (4 element) for Pentax uses upgraded multi-coated optics to double the focal length of the existing lens. Using the 2x DGII teleconverter with an 85mm f/1.4 lens, for example, will double the focal length to 170mm, which effectively sets the maximum aperture at f/2.8 (cutting the amount of light captured). Also known as a tele-extender, it serves as an excellent lens modifier that is portable, high-quality and versatile. The lens used must have a maximum aperture greater than f/4.0 in order to fully utilize its autofocus capabilities.
