The lens circuit is automatically disabled to avoid internal damage.
Remove the lens connector and check the pin connections.
Back focus adjustment
•
Camera accepts both C and CS-
mount lenses.
1. Unlock the back focus locking
button.
2. Turn the back focus adjustment as
required. (See Note 1).
3. Lock the back focus locking button.
Notes:
1. To optimize picture sharpness in
both bright and low-level lighting, it
is recommended to adjust the back focus when carrying out the
set-up procedure. The camera's unique 'Lens Wizard' allows
focusing at maximum lens opening to ensure that the object of
interest always remains in focus.
CAUTION
•
To avoid damaging the CCD sensor when using a C-
mount lens, turn the 'green' back-focus ring counter
clockwise until it stops ('Back focus adjustment')
before mounting the lens.
•
Lenses weighing more than 0.5 kg (1.1lbs) must be
separately supported.
