any
aperture
that
will bring
the
meter needle to the midpoint in the
viewfinder.
The total range of the
aperture
settings
is, of course, de-
termined by the minimum and max-
imum
apertures
of the
lens being
used.
For example, with the 50mm
f/1.4 lens and ASAlOOfilm, an aper-
ture from f/l.4 (the maximum aper-
ture of this lens) to f/16 (the mini-
mum aperture)
may be used with
any
shutter
speed
from
1 sec. to
1/1000 sec. that will bring the meter
needle to midpoint.

The exposure meter of the Spotma-
tic measures
the brightness
of the
ground glass.
Therefore, the meter
should be turned on after you have
focused your subject on the ground
glass. The following table shows the
range of the meter's light measure-
ment, and should not be interpret-
ed as the camera's
total
range
of
f/stop-shutter
speed
combinations.
As you will note from the table be-
low, with an ASAlOO film, you may
use any shutter
speed from
1 sec.
to 1/1000 sec. in combination
with
