USING SCREW-MOUNT TAKUMAR LENSES
Conventional screw-mount Takumar lenses (both Super-
Takumar and SMC Takumar) can be easily mounted onto
your camera by attaching them first to a Mount Adaptor
K. However, when Adaptor K is used, the following is
true:
1. Due to the difference in coupling systems, the
automatic diaphragm will not function.
2. Full-aperture metering lenses will function as stop-
down metering lenses.
How to Use Mount Adaptor K
1. Screw the conventional Takumar lens into the Mount
Adaptor K.
2. Attach the Adaptor/lens unit to the camera body by
aligning the red dots and , and turning the lens clockwise
until it locks with a click. (This takes slightly less than a
quarter of a revolution.)
3. To remove the lens, leaving the Mount Adaptor K
attached to the camera body, simply unscrew the lens
counterclockwise. Other screw-mount
Takumar lenses can then be attached in the normal way.
To remove the Mount Adaptor K from the camera body,
first remove the screw-mount lens. Then press, with your
thumbnail or a pointed object such as a ballpoint pen,
against the spring pin
Turn the Mount Adaptor K counterclockwise until you
feel it release, and take it out.
Since the mechanism for locking in the Mount Adaptor K
is totally different from that which locks in an SMC
Pentax bayonet-mount lens, the lens release lever on the
camera body plays no part at all. www.4butkus.org
