PENTAX Interchangeable Lenses

24mm F2.8 Standard
18mm F2.8 Wide-angle
50mm F2.8 Telephoto

Although they are the smallest
interchangeable camera lenses available,
Pentax-110 interchangeable lenses are
precision optical instruments and should be
handled with the same care given to larger
35mm format interchangeable lenses. Each
Pentax-110 lens features its own independent
focusing system. Moreover, aperture setting
is not required, as this is performed by the
diaphragm mechanism built into the camera's
automatic exposure and programmed shutter
system. Each Pentax-110 lens bayonets to
the front of the camera in the same manner.

To remove a lens previously mounted on the
camera, push upwards on the lens release
lever (Photo 1) and turn the lens approx.

85 degrees to the left until it slips out of

the mount.

To mount a lens:

1. Match up the red distance scale index of
the lens (© in Photo 2) with the red dot on
the camera body (@in Photo 2) and insert
the lens into the body.

2. Turn the lens to the right until it locks into
place (the red distance scale index should be
positioned at the top as shown in Photo 3).

Focusing

Each Pentax-110 interchangeable lens is
provided with a focusing ring and features
‘a calibrated distance scale for critical
focusing at premeasured distances. When
focusing through the viewfinder, simply turn
the focusing ring until the split image in
the center of the viewfinder aligns as one,
Lens Care

‘Although Pentax-110 Interchangeabl
Lenses are readily pocketable, they should
not be stuffed directly into a pocket
without protection as lint and dust will cling
to them: they will also scratch easily. To
‘avoid this, always cover the lens with both
front and rear caps when keeping it in your
pocket or not in use, Also make it a habit to
protect the lens from rough objects with
‘casing, cloth, etc,, when carrying it in your
pocket, and do not keep lenses in your hip
pocket or other places where they might be

‘damaged easily.

Tripod Spacer for the 50mm Telephoto
Lens

‘The 50mm F2.8 telephoto lens is much
larger than the others and will hit against
the tripod mount when the camera is
‘mounted directly to a tripod. The Tripod
‘Spacer Ring, available as an optional
accessory, is used to prevent this. To use
the spacer, simply screw it to the camera's
tripod socket; then, screw the tripod
into the socket at the bottom of
the spacer.

Lens Cleaning

Remove dust from the surface of the
lens with a blower brush, To remove smears
‘and smudges, periodically clean both front
‘and rear glass surfaces of the lens by wiping
‘them gently with lens cleaning paper or
2 soft cloth dampened in lens cleaning,
