22.5 Changing a Lens
ADVICE
Risk of damage and injury when using lenses exceeding the supported entry depth!
LPL mount lenses with more than 30.00 mm entry depth and PL mount lenses with more
than 38.00 mm entry depth might damage the camera's internal filters. Shards from broken
filter glass might cause injury.
Do not use LPL mount lenses with more than 30.00 mm entry depth.
Do not use PL mount lenses with more than 38.00 mm entry depth.
Use only lenses that do not exceed the following dimensions (left: LPL mount lenses, right: PL
mount lenses):
To ensure maximum allowable lens mounting depth always have your camera and lenses
shimmed correctly.
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.
Place the protective cap on the lens mount, when no lens is attached to the camera.
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.
