5.3.1 Viewing
Screen
Look through the lens port at
the reflection of the viewing
screen in the mirror and
check for visible dust par-
ticles. Clear the mirror shutter
so that it is rotated safely insi-
de the body by rotating at the
base of the shutter with your finger or by setting the camera to test
position, then removing the battery. Remove the viewing screen as
described in section 2.8, Changing the Viewing Screen in the Came-
ra Body chapter of the manual. Clean both upper and lower surfaces
of the screen and reinstall.
5.3.2 Eyepiece
Clean the eye lens (A), which is the outermost element closest to your
eye, by first blowing the surface with canned air, then cleaning with lens
fluid and a Q-tip. Remove the eyepiece and clean the field lens (B), whi-
ch is located on the inside of
the eyepiece, in the same fa-
shion.
5.3.3 Viewfinder
With the eyepiece off, look
into the remaining viewfinder
and clean the exposed ele-
ment of the pechan prism
using canned air or an air sy-
ringe. If dirt particles are still
present, remove the viewfin-
der assembly from the came-
ra by removing the four allen
screws that hold the base of

CLEANING
Finding the dirt
There is a simple means of
locating much of the dirt
within your viewing system:
Look through the viewfinder
with no lens on the camera
and adjust the diopter ring. If
the dust particles remain in
focus, they are most likely
located on either side of the
eyepiece. If the dust comes in
and out of focus as the ring is
moved, the dust is probably
located on either surface of the
viewing screen. Furthermore,
if the dust appears to be on
the same focus plane as the
cross hairs of the viewing
screen, it is most likely on the
bottom surface of the screen
and easily accessible.
