8 Attaching/Changing the Lens
To attach or change the lens, proceed as follows:
➡
First, ensure a clean and nearly dust-free environment.
➡
Hold the camera with the image sensor area facing downward so that no dust
will get into the camera or onto the image sensor.
➡
During the following steps, always beware not to touch the image sensor
(sensor glass), other glass elements inside the camera or the rear lens element
in order to avoid damages due to scratching or loss of image quality due to
fingerprints.
➡
Remove the camera body cap or carefully unscrew an already attached lens
from the camera in a counter-clockwise direction (first unplug the DC auto iris
4-pin connector).
➡
Remove the rear lens cap of the new lens.
➡
If necessary, remove dust from the image sensor (sensor glass), other glass
elements inside the camera or the rear lens element of the new lens using a
suitable bulb blower.
•
However, beware not to disperse dust particles inside the camera.
•
Do not use canned air.
•
Do not use organic solvents (alcohol, benzine) or cotton buds for cleaning.
➡
Carefully screw the new lens into the CS lens mount of the camera in a clock
-
wise direction and tighten it without using excessive force.
•
Ensure that the lens thread does not get stuck and the lens is not tightened
too firmly to avoid damages to the thread.
