Classic SLRs Series :
Canon F-1 - Photo-Micrography
The expansion of possibilities in close-up photography and macrophotography isj of
course, effective in creating new photographic interests in people because of their
usefulness in recording observation of various phonomena and because of the attractive
compositions obtainable and the colorful potentials they have. Particularly closeups
delight photographers because of their characteristic value in revealing the secrets
and wonders of nature which are usually beyond the sight of people. But, the maximum
photographic magnification possible in general macrophotography is 10:1, because
there are difficulties beyond that ratio due to limitations in performance of the
equipment or because suitable photographic materials are not available.
satisfy the needs for higher magnification in observation photography, the easiest
and most reasonable approach is to use the microscope, which enables to magnify even
2,000 times the actual size of objects, in combination with photographic equipment.
As a matter of fact, photomicrography has been the object of research for a long
time and many optical systems with various illumination devices, as well as exclusive
photographic accessories, have been developed. On the other hand, many conventional
cameras including the Canon SLR cameras have also been applied to photomicrography.
Canon has provided two types of connection hood to facilitate photomicrography. One
is the Photomicro Unit F for which the camera section is fixed in position, and the
other is a Macrophoto Hood designed so that the position of the camera may be adjusted.
It is used together with the bellows and copy stands so that magnification may be

to a microscope and it is convenient to use as handy accessory in photomicrography
with a fixe' camera distance. The unit is applicable to am microscope, biological
as well as metallographical whose sleeve has an outside diameter of 25mm with or
without eyepiece. The Photomicro Unit F consists of four parts: an outer and an inner
hooc tube, a light-shielding tube for the eyepiece sleev.E and a clamp ring for mounting.
Technical Data Applicable microscope: General and metallographical

of the eyepiece and the position of film.
Approximately 1/2 of the microscope's magnification Size: 107.5 x 59mm (4-1/4"
x 2-5/16"). Weight: Approx. 32Ogr. (11 oz.).
1. Release the screw that
fastens the hood andremove the inner tube from the outer tube. 2.Remove the microscope
eyepiece, then fit the inner tube and fix it by turning the knob. 3. Insert the eyepiece
into the inner tube. 4. Put the outer tube over the inner tube and fasten with the
knob. 5. Mount the camera with the outer tube bayonet following the same procedure
as for mounting the lens. 6. Just insert the light-shielding tube into the inner
tube instead of the eyepiece when it is not being applied.
