DIOPTER CORRECTION, MOUNT ADAPTER K, EYECUP P Diopter correction lenses M which fit the eyepiece on your camera are available. If you find it difficult to see the viewfinder image clearly, choose any one of the eight Correction Lenses M of -5, -4, -3, -2, -1, +1, +2, +3 diopters. Slide it into the eyepiece's accessory groove. Before buying one, try it for yourself with the lens attached to your camera. • 42 Mount Adapter K If you want to use any conventional Takumar screw-mount lens on your camera it is possible by placing an optional accessory called the Mount Adapter K between the camera body and the lens. However, please note the following conditions when actually taking pictures: • Automatic diaphragm does not work due to difference in the coupling system. • Stop-down metering must be made. • Automatic aperture setting with a Pentax dedicated flash is not workable. Eyecup P The Eyecup P is attached to the viewfinder accessory groove. When using such accessories as "Diopter Correction Lens M," "Viewfinder Cap," etc., remove the Eyecup P from the camera.
