Appendix E: Mounting and Focusing C-
and F-Mount Lenses
This appendix provides information about the mounting and focus of C- and F-mount
lenses.
E.1 Lens Mounting
C-mount lenses simply screw clockwise into the threaded lens mount at the front of
the camera. In mounting a C-mount lens, tighten it securely by hand (no tools).
To mount an F-mount lens on the camera, locate the large indicator dot on the side of
the lens. See
Figure E-1 .
Figure E-1: F-mount (Nikon) Lens Adapter
There is a corresponding dot on the front side of the camera lens mount. Line up the
dots and slide the lens into the mount. Then turn the lens counterclockwise until a click
is heard. The click means that the lens is now locked in place.
Removing either type lens is equally simple. In the case of a C-mount lens, rotate the
lens counterclockwise until it is free of the mount. In the case of an F-mount lens, press
the locking lever on the mount while rotating the lens clockwise until it comes free and
can be pulled straight out.
Both types of lenses typically have provisions for focusing and aperture adjustment,
with the details varying according the make and model of the lens.
CAUTION!
!
Always begin with the lens stopped all the way down
(largest f/ stop number) to minimize the risk of overloading
the intensifier.
