®
When a lens with an automatic diaphragm is used, the image
in the viewfinder is viewed with the aperture diaphragm of the
lens wide open. However, pressing the depth-of-field preview
lever will cause the lens to be stopped down to the
fin umber set
to enable you to examine depth of field before shooting _ The
image in the viewfinder " darkens " according to the selected
f/number-the smaller the aperture (i.e., the larger the fl
number), the " darker" the image. Components of the picture
that appear in focus when the lever is pressed wi ll be in the
zone of sharp focus.
Note: Be sure to press the depth-of-field preview lever fully. Also, release
the lever when you depress the shutter release button.

®
This device is useful in self-portraits or when taking a picture of
yourself with other people. Set the self-timer by turning the lever

photo. This can be done either before or after the film is ad-
vanced . After the self-timer has been set, press the shutter
release button. Reflex mirror
@
will go up and the self-timer will
start to operate ; the shutter is released after a delay of approx.
10 sec. If you wa nt to cancel self-timer operation after the lever
has been set, move it back to its original position with your
finger. You can then take the picture the standard way as before.
However, turning the self-timer lever when it is already in
operation will result in the shutter's being released the moment
the lever is back in its original position . Except for B (bulb), the
self-timer can be used at any shutter speed .
