 When  the camera   is opened,  the  op-
 tical   finder  13  springi   up  into  po_
 sition.  Use   it  for  preference,  since
 shots  at eye  level   will  then  have  the
 most  natural  perspective.
 Hold  the camera as in  figs. 11 and  12,
 i.  e.-press   it  firmly  against'the   face             l
 and look  through  the rear lens  of the
 finder.        The                 front                      lens                            indicates                                       the                   IF'r       angle exact                 of                   view.                      The                            whole  rim
 of  this  lens  must  therefore  be   vi-
 sible.
 For pictures  in the half-size, 2r/+ X  Is/e
 ins., bring  up the small  size mask  jn_
 to  the  frame;  this mask  is hinqed  to
the front  portion  of the  finder.Close  the  finder  by  simply  pushing   _
down   the   cover,  db  nof   iorictr   the
lenses.

     IV. Unloading
          l,  After  making  the  last  exposufe,
         turn on  until  the protective  paper
          is no  longer  visible  in  the  lower
         film  window.
 *    2. Open the back of the camera, hold
        the end of the paper securely and
         carefully  turn  on  the  film  key  a
        short  distance. The  film  wilt  thust*.       be wound  tightly;  loosely  wound       'rr'I         films are susceptible to light, while
       on the other hand films wound too t       tightly  will  become scratched.

    ing without a Focar lens, i. e. it needs
    merely be lengthened  in  proportion
     to the aperture. When using a Focar
    lens the view  finder does not  give
    the exact size of the actual picture. As
     figure 14 shows, the actual picture will

    taining  attractive  landscapes, since
                                                                                                                 a    t7

This indicates that' they are "coated"
        i. e. fitted with
              "anti  retlection  laYers".T#    The AR  layers  obviate  reflection  of
      light  rays  as a  result  of  "counter-
     light"   i. e. they reduce  it  to a mini-
    mum; at the same time they increase
     the brilliance  of the pictures and the
    transmission power  of the lens.
    Even uncoated Ienses require  verY
     careful  treatment;  the  outer  surfaces
     of lenses with AR  laYers should be
     treated with especial care. These lay-
     ers are very  hard, but theY are ex-                         1/ro     tremely thin (aPP.   ooomm.)
    The lens must be cleaned with a fine
                    very soft cloth. GreaseI  hair brush or a
    and  oil  stains may  be removed bY
