Appendix E: C- and F-Mount Information
This appendix provides information necessary in order to use C- and F-mount lenses with a
PI-MAX4 camera. Both types of lenses typically have provisions for focusing and aperture
adjustment, with the details varying according the make and model of the lens being used.
Before installing a lens, always begin with the lens stopped all the
way down (i.e., the largest f/ stop number,) in order to minimize the
risk of overloading the intensifier.
E.1 C-Mount Lens Information
This section provides information about mounting and removing a C-mount lens.
E.1.1 Installation
C-mount lenses simply screw clockwise into the threaded lens mount at the front of the
camera.
When mounting a C-mount lens, be sure to tighten it securely
by hand - never use any tools.
E.1.2 Removal
When removing a C-mount lens, rotate the lens counterclockwise until it is free of the
mount.
