Teleplus 2x Pentax PZ-AF MC7 DG Digital SLR fit Tele Convertor Lens + Free Bag
Digital Ready DG model - see below re AF. If used with lenses with a slower aperture (e.g F5.6, F6.3 etc) then yes it will still physically fit and double the focal length, but you will need to focus manually, there will be NO Auto Focus.
