F-Mount
Flange focal distance is the optical distance from the mounting flange to image
sensor. Prosilica GX F-Mount cameras are optically calibrated to a standard 46.5
mm optical flange focal distance.
Adjustment of F-Mount
The F-Mount is adjusted at the factory and should not require adjusting. If for
some reason, the lens mount requires adjustment, use the following method.
Attach F-Mount compatible lens
Use an F-Mount compatible lens that allows an infinity focus. Attach the lens to the
camera using a counter-clockwise rotation of about a quarter turn. The lens should
snap into place and the lens flange and camera flange should mate over the full
circumference.
Loosen F-Mount front assembly
Use a 1.5 mm hex wrench to loosen the 3 set screws that hold the F-Mount front
assembly to the camera body.
Adjusting the lens to infinity
Precondition: Use a F-Mount compatible lens that allows an infinity focus.
1.
Set the lens to infinity and image a distant object (10 to 15 m). Make sure the
lens is firmly threaded onto the F-Mount ring.
2.
Rotate the lens and F-Mount ring until the image is focused.
3.
Carefully tighten the locking ring and recheck focus.
