shutter tensioning and automatic aperture control system of the lens to
the camera mechanism. The tubes must thus be fitted in the same way
as the lenses, with the coupling shaft lined up with the red dot inside the
tube.
Similar tubes, but without the coupling system are available for the F
models.
The linear mirror unit is used in photocopying when extremely accurate
parallel alignment between the plane and subject is essential. It is accurate
to within two minutes of arc.
The micrometer adaptor connects the Hasselblad directly with the eyepiece of the
microscope for photomicrography.
A special microscope shutter is available to fit between the camera and the
micro adaptor (left). This has no lens, and merely pro vides a means of
controlling the exposure . Alternatively the rear auxiliary shutter of the
camera can be used. A lens mount adaptor is also available for certain special
lenses on the camera (right)
Extension Bellows
The extension bellows for the Hasselblad acts in the same way as the tubes but provides a valuable extension between 3 in. and 8 in.
It is intended for large close-ups, macrophotography, and copying of small originals (e.g. postage stamps).
The bellows unit for the Hasselblad 500C has bayonet mounts for attachment to the camera and to take the lenses. It is supplied with
a double cable release for the operation of the lens and the camera mechanism. The lens is tensioned manually with a setting arm in
