7. You'll notice a metal shim on the bottom, leave it there. You should have the parts as shown below (note the
metal shim was removed for illustration purposes only). Note that when you place the focusing screen on the
table, the back should be slightly lifted up due to the protruding extensions on the bottom.
8. Using an air blower, blow off any dust on both sides of the screen. Handle the focusing screen with one finger on
each side gripping the sides only to prevent oil from getting on the screen itself.
9. Before reinserting the focusing screen ensure that the metal shim that was left inside the camera is flushed to the
back, otherwise the shim will obstruct the viewfinder.
10. Insert the focusing screen back into the camera with the tweezers first angling it into place with the tab on the
back end of the screen inserted into the slot then drop into place. Ensure that the focusing screen is fitted
correctly and not at an angle.
11. Install the metal bracket in the same manner, at an angle where the two metal tabs on the back fits into the
appropriate slots then drop. To firmly put the metal bracket in place, push the tab towards the back using the
tweezer then down. The tab should “click” into place. Ensure that the metal bracket is aligned correctly.
12. Place the lens back on the camera and turn on the camera. Check that all focusing points are lit correctly by
selecting the 7-point focus. If any of the red dots are misaligned, most likely the focusing screen has been placed
in reverse. If you see a portion of the bottom screen blocked this indicates that the metal shim has shifted and
needs to be aligned against the back of the camera.
