OTHER FOCUSING METHODS
Distance scale
You may find that in certain
situations it is easier to focus by
estimating the distance to your
subject, then aligning the corre -
sponding figure on the distance
scale
with the index, such as :
• When
taking long exposures or
flash pictures when it is too dark
to focus through the lens
•
If you want to prefocus on your

photos

For proper focus when using

distance scale with the . small red
dot (or red "R" on Me and old -

Film-plane index
The symbol beneath the film -
advance lever indicates
the position
of the film inside the camera. Th is
mark can be used for measuring the
distance from subject to film when
taking close-ups, photomacrographs ,
and photomicrographs, where the
exact distance is sometimes impor -
