USING SCREW-MOUNT TAKUMAR LENSES Conventional screw-mount lenses can be easily attached to the lens mount of your Pentax Super Program by using the optional Mount Adapor K. But there are some limitations. • Put the Mount Adaptor K in the body mount by matching both marks. • To lock it, rotate the adaptor clockwise (65') with a pointed object such as a ball-point pen. Now your Super Program can accept any conventional Pentax screw-mount lenses. • To remove the adaptor, press the spring pin on the adaptor with some pointed aid and rotate it counterclockwise until it stops. Limitations in using screw-mount lenses on the Super Program • The distance scale of the lens is usable as it is, up to infinity ( ). • Automatic diaphragm coupling doesn't function due to the difference in coupling system. • The exposure is metered with aperture stopped down. • Programmed AE and Shutter-priority AE modes cannot be used with screw-mount lenses. • There is not automatic aperture setting even with dedicated flash units. • s04 yye 0 • 57 •
