Correct focus cannot be achieved using a CS-mount lens on a C-mount camera.
Example C-mount Cross Section
Back Flange Distance
The Back Flange Distance (BFD) is offset due to the presence of both a 1 mm infrared cutoff (IRC) filter and a 0.5 mm sensor package window. These two pieces of glass fit between the lens and the sensor image plane. The IRC filter is installed on color cameras. In monochrome cameras, it is a transparent piece of glass. The sensor package window is installed by the sensor manufacturer. Both components cause refraction, which requires some offset in flange back distance to correct.
The resulting C-mount BFD is 17.99 mm.
The resulting CS-mount BFD is 12.52 mm.
For more information about the IRC filter, see Infrared Cut-Off Filters.
