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.
