FOR BEST RESUtTS
       '      Toron Auxiliory Lenses will provide highly sotisfoctory
   results if the following foctors ore token into considerotion.
      There is o tendency for ouxitiory lenses to " vignette " or
                                                              ore'  .cut off corners of the negotive oreo, especiolly if they
 . mounted foo for from the surfoce of the comero's prime lens.
  .The insertion of  filfers between the prime ond ouxiliory  '.i.ns"s       roy   result in morginol imoge cul-ofi by increosing the
  distonce between the two lenses.
  .    For moximum definition ond imoge shorpness when using
  ouxiliory lenses, use lens openings f z 4.5 or smoller (f r 5.6,
  "f :6.3, f :8, f : I l, etc). When softer results ore occeptoble,  '  lorger lens opertures moy be used.


     Reod these insfrucfions ogoin corefully.    lf your results
 '. ore not completely sotisfoctory, you hove not followed the
  directions occurofely. Ggod shooting ond odded comero
  cnioyment will be obtoined when Toron Auxiliory Lenses ore
