ANGENIEUX ZOOM LENS

applied very lightly moving from the center
surface of the lens towards the edge.
The recommended cleaning agents are the
following:
1. A camel -hair brush.
2. Slightly
moistened Kleenex balls or
dust -free surgical swabs. The moistening
agent should be breath moisture, denatured
alcohol, ether, or acetone.
CLEANING THE GLASS SURFACES
1. Before applying any lens cleaning agent,
first remove all dust particles by using a
syringe.
If this method fails, use a soft
camel -hair brush; however, it is suggested
that
the brush be tapped on the edge of
the Camera pedestal to remove the ac-
cumulated dust particles after each pass
of the brush.
A soft, clean, dust -free cloth can also
be used to remove dust particles. Rotate
the finger when wiping. If you are cleaning
the optical surfaces from right to left, ro-
tate the finger clockwise, and if wiping left
to right, rotate the finger counterclockwise.
