Fog-proof filter
Depending on the temperature and humidity, the
protective filter may fog up, particularly if you breath
near it. To ensure that the viewfinder is always clear,
replace the protective filter with a fog-proof filter (Part
No. 1-547-341-11), not supplied).
Fitting the fog-proof filter
Detach the protective filter from the packing ring, then
replace it with 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.
