• BELLOWS UNIT I
Extremely flexible for ultra-close-up photography, the Bellows
I permits use of the camera's own lens. Provided with a special
precision-calibrated gear shaft for reading continuous
magnification from 0.62 to 2.45 with the standard 55mm lens.
• AUTO BELLOWS & SLIDE COPIER
The Asahi Pentax Auto-Bellows is a highly flexible close-up
and macro-photographic instrument. The bellows extension is
longer than the extension of the standard Bellows Unit. The
Auto-Bellows is more versatile. With the double cable release
supplied with the Auto-Bellows, you release the shutter and
activate the automatic diaphragm simultaneously if you use a
fully automatic diaphragm lens. With its lens reverse system,
you can use a lens in reversed position for higher macro
resolution.
The geared rail of the Auto-Bellows is meticulously engineered
with high precision. The freely movable tripod seat underneath
the rail rod maintains the whole equipment on tripod in
complete balance. Micro-action extension knobs are equipped
on the camera body and lens sides for precise bellows
extension.
The Slide Copier attaches to the front end of the Auto-Bellows
for easy duplication of color films
With the Bellows-Takumar 100mm f/4 lens, you can
photograph from 1.32X magnification to infinity ( ∞ ). You
easily obtain high magnification with a 28mm to 35mm lens.
By adding the standard Bellows Unit or Extension Tubes to the
front or back of the Auto-Bellows, you can reach 10X to 20X
magnification.
The Asahi Pentax Auto Bellows is a precisely designed close-
up and macro equipment for professional photographers,
research workers, scientists and specialists in close-up and
macro works.
