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.

Set the Mirror Lock-up Lever to its ‘SQUARE’ position.

Remove the lens.

Slide the Focusing Screen Release Pin (1) to the left using the focusing

screen tweezers. The Focusing Screen Frame (4) will drop down.

Remove the focusing screen from the Focusing Screen Frame by

grasping the focusing screen’s tab (3) with the tweezers, and then

lifting the focusing screen up and out of the Focusing Screen Frame.

Store the screen in a suitable container so that it won’t be damaged.

Using the focusing screen tweezers, grasp the replacement screen by

its tab (3), and then position it into the Focusing Screen Frame (4).

Carefully push the Focusing Screen Frame (4) up until it clicks and locks

into place. Be careful not to damage the screen.

Install the lens.
