Interchangeable Viewfinders; Changing The Focusing Screen - Pentax LX Quick Help/Reference Manual

The Pentax LX system includes different types of accessory grips.
Accessory Grip B is hand-contoured for added balance and handling
convenience. For more precise requirements, the Accessory Grip A can be
shaped to meet the photographer's individual needs using a whittling knife
or similar instrument and sandpaper to smooth out the rough edges. To
attach either grip, first place the grip over the accessory lug C making sure
the screw aligns with the socket at the bottom front of the camera F.
Tighten the screw using a screwdriver or coin.

CHANGING THE FOCUSING SCREEN

Accessory Grip A
Super-Takumar and SMC Takumar screw-mount lenses can be attached to your Pentax LX
by using the Pentax Mount Adaptor K. When using this accessory, however, the automatic
diaphragm of the lens will no longer function and meter readings must be made with the
lens apertuPe stopped down.
Mounting The Adaptor
After attaching the Adaptor K to the lens until it seats firmly in place, align the red dot on
the Adaptor with the red dot on the camera's lens mount. Insert the lens and rotate the
adaptor/lens combination clockwise about 1/4 turn until in clicks into place. The Mount
Adaptor K is now fully engaged and screw-mount lenses can be interchanged freely
without further adjustments.
Removing The Adaptor
After removing the lens, press the adaptor release A with your thumbnail or a pointed
object such as a ballpoint pen. Turn the Mount Adaptor K counter-clockwise until you feel
it release and remove it from the lens mount. Please note that the lens release button B
serves no function when using this adaptor.
