Using the Depth of Field Scole
  Depth of Field is the distonce, toword ond owoy from
the comero, within wh ch everything will be in shorp focus,
depending on how much the lens operture is opened up
or stopped down, ond on the distonce set on the focusing
scole. The Depth of Field decreoses the wider the lens
is opened up ond the closer the subiect to be ohotogroph-
ed is brought to the comero, ond vice verso. This relo-
tionship con be better understood,  if you will octuolly toke
reodings of the Depth of Field Scole (S). Assuming thqt
your lens opening is set ot f/B ond your comero is focused
on the tip of somebody's nose exoctly five feet owoy, then
everything not more thon 6 feet owoy or not closer thon
obout 4.3 feet from the comero will be in shorp focus, ono
the Depth of Field (permissible toleronce) will be qbour
1.7 fi.  With your comero in focus ot the some distonce
but with your lens opened up fully (fi3.S) you hove bur
0.7 Il. or so leewoy to get o shorp picture. Conversely,

Bulb (press button to open shutter, releose to close) is olso
ovqiloble. The vorious settings ore obtoined by turning
the shutter Speed Lever (.|0) to the desired position on
the scole. (N.B. With the  I i500 sefting it is beiler ro
moke the od[ustment before the shutter hos been cocked,
thot is, ihe Film Wind Knob hos not yet been turned ofter

socket (9) directly under the shuter Bufion (7) enobles you
to use o coble releose or o self-timer.
