67 INTERCHANGEABLE LENSES
PENTAX
Asahi Optical had its beginnings as a
lens maker and today
is the world 's only
leading lens maker manufacturing a large
format camera. All 67 interchangeable
lenses are computer-generation optics
designed in the Company's
own engin-
eering department, manufactured in its
own factories, and tested in its own labo-
ratories. Meticulous quality
control over
each step
of the manufacting process as-
sures maximum optical performance
with
every lens in the line.
67 lenses truly exist in a class of their
own. Giants in
terms of quality, precision
and
power , each features a precision ba-
yonet
mount which matches up with the
camera perfectly, and each up
through
800mm focal length offers fully automatic
diaphragm . In addition , each is of rugged
and durable construction
for years of .
reliable use.
They also incorporate a host
of ingenious features geared toward max-
imum operating ease.
Another outstanding feature of the 67
lenses is Super-Multi-Coating, Pentax's
own unique 7-layer coating process which
increases light transmission for brighter
and crisper images, and also minimizes
flare and
ghost images.
Please refer
to the sections of these
instructions concerning the lens
or lenses
you have purchased. Lenses
with com-
mon characteristics are listed
at the begin-
ning
of the various sections for con-
venient reference
as you thumb through
the manual. Sections where no listing is
given are general instructions
for all
lenses; there are also sections devoted
to special purpose lenses (see "Con-
tents").

remove the lens from the camera body.
Lens
Mounting : Align the red dot of the lens
with the red dot of the mount and insert the
bayonet tabs
as illustrated in Photo B. Turn

All these 67 Lenses match with the outer
bayonet mount of the 6 x 7 camera.
To Mount: Loosen the fastener ring surround-
ing the lens mount and position it with the
white dot facing upward (Photo C). Then,
match the lens mount with the outer bayonet
mount of the camera, insert the bayonet tabs
and
turn the fastener ring to the ri ght as
illustrated in Photo D.
Note : Check that the lens is mounted securely
before
letting go . If the bayonet tabs have
not caught properly , the lens may fall off when
you let go

67 lenses are high precision optical in-
struments and should be treated accordingly .
Protect them from humidity , salt air and dust;
do not store them in damp places. It is good
practice to protect the lens with a filter when
using it near the seashore and other loca-
tions where dust or moisture might accumu-
late.
Cleaning: Do
not wipe the lens with a hand-
kerchief or other rough cloth which might
scratch the surface. Use only a rubber blower
or soft brushes especially designed for lens

cleaning for removing dust from the surface of
a lens. To remove most of the dust, wipe it
away or brush it away gently as shown in the
photo on the left .
If you should fingerprint a lens surface, or if
it is too dirty to clean with a blower, clean the
lens with either high-quality lens cleaning paper
or a very
soft cloth wrapped around the end
of a match stick, etc. The cloth or paper can
be dampened
with lens cleaning solution or
alcohol. Wipe gently with a circular motion
from the center outward . When cleaning
larger lenses,
wrap the paper or cloth directly
around your
finger to clean more effectively.
With extremely dirty lenses, shift the cloth or
paper frequently to avoid wiping the dirt back
onto the lens. A few wipes in this manner
should remove
most stains. If gentle cleaning
fails
to remove a stain, the lens should be
taken
into an authorized Pentax Service Center
for servicing.
Excessive heat,
dropping and scratches will
also damage lenses. Exercise care so
as not
to drop lenses and do not toss them around
carelessly. Always cover a lens
with both front
and rear caps when storing it away in its case
or bag.
When not using lenses regularly, especially
during humid weather, remove it
from its case
and check
for mildew. Dry out the case if
necessary. Light mildew can easily be wiped
off . If mildew has formed on the inside of the
lens, the lens may require repair.

67 lenses from 400mm through 800mm
telephoto (except 500mm f / 5.6) feature a
manual
diaphragm which is stopped down by
rotating
the aperture ring to the various
click-stop f-
number settings. This method is
used
with all long telephoto lenses, except
the
1000mm reflex telephoto which does not
employ a diaphragm . When using manual
diaphragm lenses, focus
with the lens set at
maximum aperture, and
then stop it down to
shooting aperture just before tripping the
shutter.
Preset Diaphragm
The SMC Pentax 75mm shift lens features
a preset
diaphragm system, whereby the
shooting aperture is preset with a preset
ring,
so focusing and composition are per-
formed at full-aperture. Then, the aperture
is
stopped down for exposure metering and
shooting by turning the aperture ring until it
matches up with the preset ring, (Operating
details are given in
the instruction manual
furnished
with the lens.).

hoods are available for the various
67 lenses. Certain hoods may be used
interchangeably , some fit only one lens, wh i le
others are built-in .
Screw-mount lens hoods : The 90mm and
105mm lenses take the same lens hood;
likewise, the
135mm and 150mm lenses.
In
both cases, after screwing the hood into
the threads at the front of the lens as far as
it will go, loosen it slightly so that the angle
of the hood is square with the camera body .
Spring - type hood: The lens hood for the
55mm f/ 4lens is a spring type which clips
to the front of the lens easily via two tabs.
Bayonet - mounting lens hood : The lens hood
of the 75mm f/ 4.5 lens attaches to the lens
via a
two tabbed bayonet fixture . Match up
the white dot on the lens hood with the
white dot on the lens barrel and turn the
hood to the right until it locks in place.
