MULTISYSTEM ASTROCAMERA 4x5 FORMATCompleted
The Multisystem Astrocamera L was made specifically
for use with wide lens image circles and
optical systems. It was made for optical
systems from the 6x7/6x9 to the 4x5. The
MULTISYSTEM ASTROCAMERA S was made for 35mm
camera lens, 645 camera lens and small image
circle telescopes. The Film holder was made
for the 6x7,6x9.
Consequently, THE MULTISYSTEM ASTROCAMERA 4x5 FORMAT was made specifically for use with large
4x5 image circle, large size lens astronomical
telescopesiKoheisha's 150mm F6.5) and the
like.
As with with prior Multi-system astrocameras,
this Multisystem Astrocamera 4x5 Format can
be used with a variety of optical systems
by changing the mount.
Although the cameras in these 2 photos are
for the S Jimmar HM F5.6/210mm, the CM Fujinon
300 lens is attached as a dummy. In use with
the 300mm lens, there is an additional ring.
In the photo above, for the 4x5 big type
lens, the mount@consists of 3 parts, a main
part-lens board connecting ring (upper right),
lens board (upper left) and fixed focus ring
(lower left).
By changing the lens board, it can be used
for 150-220mm 4x5 lens. For lenses of greater
focal length, an additional ring is needed.
Moreover, it can be used for lenses of 90mm
more or less, by changing the main part-lens
board connection ring and lens board.
The photos below show the 150mm F6.5 use
MULTISYSTEM ASTROCAMERA 4x5 FORMAT.
The photo below shows, A Camera main part,
B control ring and C the mount.
with the MULTISYSTEM ASTROCAMERA L, MULTISYSTEM ASTROCAMERA S(6x7 / 6x9)
and
MULTISYSTEM ASTROCAMERA 4x5 FORMAT,
the MULTISYSTEM ASTROCAMERA has been serialized. It can be seen that
with only a few main parts, as many optical
systems as possible can be made.
