Changing Focusing Screens
CAUTION
Since the focusing screens’ surfaces are made from plastic and are soft and easily damaged, be
sure to handle them carefully.
Never touch the surface of a screen with your bare fingers.
To remove dust, blow it away using a bulb-type blower. Do not use canned compressed air, as
this may leave a propellant residue on the screen.
Clean the screen with a soft, lint-free cloth and a small amount of ether or benzene. Do not use
petroleum-based solvents, ketones or paint thinners to clean a screen.
