Angle Finder A2 and B
The angle finder slips over the viewfinder
eyepiece. It rotates 90 degrees so that the
image on the viewfinder can be viewed
directly from the side or above whenever
it
is inconvenient or impossible to look directly
through the eypiece. This i s very helpful i n
copying, close-ups, macmphotography, and
photomicrography. There are two types, the
A2 whose image is reversed as in a mirror, and
the more advanced Angle Finder B with the
normal camera image.
Magnifier S
The Canon Magnifier S gives 2.5X magni-
fication of the viewfinder center for precision
focusing in close-up work. The power can
be adjusted t o your eyesight within the range
of +4 t o -4 diopters.
The Magnifier
S
combined with its
adapter can be inserted into the grooves of the
viewfinder eyepiece. The adapter of the
Magnifier
S
is hinged t o allow the magnifier
to swing upward from the eyepiece leaving the
whole screen image visible after focusing.
