lnterchangeable
The Asahi Pentax offers many inter-
changeable lenses in a wide variety
of focal lengths, all of which are high-
ly respected by both professional and
amateur photographers for their fine
resolution. The photographic cover-
age of the various Takumar
lenses
is illustrated on page 25. With focal
length longer than 55mm, the subject
image is seen through the viewfinder
larger than its life size.
Regardless of the lens selected for
your Asahi
Pentax, there
is never
need for
an accessory viewfinder,
ordinarily
required
for rangefinder
type cameras.
When interchanging lenses, hold the
lens by the distance scale ring. When
attaching a lens, filter, or lenshood,
do not screw it too tightly,
3s you
may find it difficult to remove.
Lenses
Fixed Focusing Setting
Because of the considerable depth of
field of wide-angle lenses, ]-ou can use
them as fixed focus lens if the dia-
phragm and distance scales are set
properly.
For your convenience, the
Super-Takumar and SMC Takurnar
lenses shown on pages 26 and 27
(marked rvith * ,i have a fixed focus
mark.
Just align with the index the
orange-coloured figures of the dia-
phragm and distance scales, and the
lens n'ill be in fixed focus from fore-
ground to infinity. You'll find this ex-
tremely convenient for fast shooting.
Super-Multi-Goated
(SMG ) Takumars
Pentax SMC Takumar lenses are
the world's first 7 -layer multi-coated
lenses. A truly remarkable optical
achievernent. Conventional lenses
have only 1-3 layer coatings. The
additional coating of SMC Takumar
lenses let in more lighting resulting
in truer colours. Ref lection is re-
duced to 0.2% allowing the remain-
ing 99.8% of light to pass through.
This means higher light transmis-
sion, and the brightest lens possible.
Colours pass through with equal in-
tensity so colour balance is strikingly
improved. Brighter blues. Vibrant
reds. Truer yellows. SMC Taku-
mar lenses make it possible. And,
no ghosts or flares even when shoot-
ing against the sun. Ultra violet
light is reflected off the glass sur-
face. So, only true colours are ab-
sorbed. Undesired rays are kept out.
SMC Takumar lenses are for people
interested in the ultimate in photo-
graphic lenses.
