ADVICE
Dust particles on the sensor cover glass may affect the recorded image!
When no lens or lens cap is attached to the camera, dirt and dust particles may enter the
camera and settle on the sensor cover glass. Particles on the sensor cover glass can later
be visible in the recordings made by the camera.
Changing lenses or lens mounts should be done in a dry and dust-free environment. If this
is not possible, take extra care that no particles enters the camera while the lens or the lens
mount is off.
After removal of a lens, perform a dust check to make sure no particles have settled on the
sensor cover glass..
When no lens is attached to the camera, use the lens port cap to prevent dust from entering
the lens cavity.
Always store the camera with a capped lens mount or camera front cover installed.
Make sure to protect all optical surfaces when changing a lens or lens mount.
► Switch off the camera and unplug any power source.
► Crosswise, loosen all four lens mount screws with a 3.0 mm
Allen key.
► Carefully remove the lens mount (or camera front cover).
► Store the lens mount in a case for dust protection.
► Carefully align the lens mount with the
two guiding pins (5, 6) on the camera's
lens mount base.
► Crosswise, hand-tighten all four lens
mount screws with a 3.0 mm Allen key.
