Loosen the locking ring
Use an adjustable wrench to loosen the locking ring. Be careful not to scratch the
camera. When the locking ring is loose, unthread the ring a few turns from the
camera face.
Adjusting the lens to infinity
Precondition: Use a C-Mount compatible lens that allows an infinity focus.
1.
Set the lens to infinity and image a distant object (10 to 15 meters). Make sure
the lens is firmly threaded onto the C-Mount ring.
2.
Rotate the lens and C-Mount ring until the image is focused.
3.
Carefully tighten the locking ring and recheck focus.
