Dust or dirt on the viewfinder will never impact the image quality, but can be
quite distracting during a shooting session. Detach the viewfinder and first try
to remove the dust with a rocket air blower. Then, if there is still some debris or
smudges, simply moisten a lens cloth to wipe the smudges away. It is easier to
clean the diopter if you remove the rubber eyepiece first by grasping the sides
and pushing it upwards. Remember to clean the large glass plate at the
bottom of the viewfinder too.
Note: Never use chemicals as they might leave streaks on the viewfinder.
Focusing Screen
The focusing screen is a very delicate part that can easily be damaged. If you
observe any dust or dirt on the top outside of the focusing screen, you can
gently try to remove it with a rocket air blower. If the dirt seems stuck, do not
attempt to use force to remove it, but instead contact your reseller or a service
center for guidance on how to get it cleaned. If you observe dust or dirt on the
inside of the focusing screen, you should also contact your reseller for
guidance.
WARNING: Never use compressed air to clean the focusing screen unless the
product is made specifically for photographic equipment and do not touch
the screen with any tools or your fingers. Scratches to the focusing screen is
permanent and cannot be removed.
