Using Screw-Mount Takumar Lenses - Pentax PROGRAM PLUS Manual

USING SCREW-MOUNT TAKUMAR LENSES
Conventional screw-mount lenses can be easily
attached to the lens mount of your camera by
using the optional Mount Adaptor 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 camera 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.
