Whether your AKARETTE is equipped with o lens with o moximum operture of

you will find in eoch cose thot you hove in your possession on obiective of the

The lens mount corries three scoles:
1. The diophrogm scole with the engroved  f numbers (opertures or stops) +116,11,

On the front of the lens mount on internol threod is provided for the screw fitting
of o Lens Hood, Supplementory Lenses or Colour Filters. In modern photogrophy
the moin purpose of o diophrogm is to vory the depth of field, thot is to soy the

Chonging of Lenses
   The lens is fixed to the comero by o knurled locking ring which is the first ring in
    front of the shutter. lf you wish to chonge the lens toke the comero in your left
    hond, unscrew the knurled locking ring onti-clock-wise, toking core noi to grip the
   diophrogm ring ot the some time. Just o little more thon one revolution ond you
   con remove the lens. When replocing it moke sure thot the smoll recess on ihe rim
   on ihe bock of ihe lens mount lies opposite the pin in the lens corrier. Slip the lens
   home ond turn the knurled locking ring clockwise until it is tight.
   Toke every core not to touch the lens (gloss surfoce) with your fingers. The
   greosespots you leove moy be very slight, but they will interfere seriously with
   the quolity of your pictures. To cleon the lens, use only o soft, cleon piece of
    linen or o cleon gloss-polishing chomois.

The AKARETTE is equipped with o precision Sector type shutter ond its speed

The speeds of the AKARETTE  ll ore os follows: B (time-boll),  1 ,tlr,'lu,rlru,1lrs,rluo,

You do not hove to worry obout cotking the shutter os this is done outomoticolly
by turning the film winding knob in theAKARETTE. The film con only be odvonced
