Cleaning the Screen or Interior
To clean the screen or internal mirror of the
viewfinder, detach the viewfinder from the camera,
detach the viewfinder barrel from the body, and clean
as explained below, taking care not to damage the
components.
For information about detaching the viewfinder from the
camera, see the procedure explained in “Attaching the
Viewfinder to a Camera” on page 9 (E).
For information about detaching the viewfinder barrel, see
the procedure explained in “Detaching the Viewfinder
Barrel” on page 12 (E).
To remove dust from the screen or the mirror
Use a dust blower.
To clean the lens or the protecting filter
Use a commercially available lens cleaner.
Notes
•Do not use organic solvents such as thinners.
• To protect the eyepiece from moisture and prevent
the protective filter from coming off, be sure to
always attach the eyecup.
• To assure protection from moisture, attach firmly
when attaching the protective filter to the packing
ring and the eyecup to the eyecup holder.
Disassembling the eyepiece for cleaning
1 Detach the eyepiece from the viewfinder barrel.
For the detaching procedure, see “Detaching the
Eyepiece” on page 11(E).
2 Remove the eyecup from the eyecup holder.
3 Remove the protecting filter, together with the
packing ring, from inside the eyecup holder.
4 Detach the protecting filter from the packing ring.
Fog-proof filter
Depending on the temperature and humidity, the
protecting filter may mist, especially if you breathe
near it. You can replace the protecting filter with an
optional fog-proof filter (Part number: 1-547-341-12)
to prevent the fogging.
Attaching the fog-proof filter
Remove the protecting filter together with the packing
ring, and in their place attach the fog-proof filter.
Note
When cleaning the fog-proof filter, wipe the filter very
gently with a soft cloth to avoid impairing the anti-
fogging effect.
Check the viewfinder after using it in
harsh environments
Check the following points after using the viewfinder
in a harsh environment such as a beach, a dusty area,
or a hot spring resort.
•Use an airbrush to carefully remove any dust or sand
from inside the viewfinder.
• Salt from seawater or sulfur from hot springs can
result in whitish corrosion on the non-painted
surfaces of the viewfinder. Use a cleaning solution
such as ethanol to remove any adhering salt or sulfur
from the non-painted surfaces as soon as possible.
•Clean the contacts of the connector.
•Check that the viewfinder is working correctly.
