A3 F-MOUNT ADAPTER (OPTIONAL)
A3.2 CHANGE FROM C-MOUNT TO F-MOUNT
Instructions on how to change the optical input from C-mount to
optional F-mount:
Step 1: Remove C-mount Adapter
Loosen the hexagon socket screws and unscrew the C-mount
adapter counterclockwise.
Step 2: Insert F-mount Adapter
Screw the F-mount adapter ring in gently, but not completely,
because back focal length still has to be adjusted.
Step 3: Adjust Back Focal Length
First of all, attach a lens to your F-mount adapter. Then set the focus
of your lens to infinity. After that, look for an object in infinity* and
generate a sharp image by turning the adapter. Then fix this position
by turning the black ring clockwise. Finally, check again if the
sharpness is perfect.
*rule of thumb: object should be away about 2000 times the focal length in mm
Limitations of C-mount Lenses
Keep in mind that C-mount lenses could cause shadings at the edges
of big sized sensors. Most C-mount lenses are able to illuminate a
maximum image circle of 11 mm (2/3”), 16 mm (1”) or 22 mm (4/3”)
diameter only. The pco.panda has a sensor diagonal of 18 mm, it
follows that you have to use the ROI function for a shade less image
while using the C-mount adapter with the two smaller C-mount
diameters.
