c. Lens and shutter assemblies and lens caps. The lens and shutter
assemblies furnished with the camera set are mounted on individual lens
boards (figure 7). Each shutter is fitted to accept a cable release and has
a builtin adjustable time delay synchronization mechanism for synchronized
flash photography. The glasstoair surface of each lens is coated to
reduce internal reflections. A pair of velvetlined lens caps (front and
rear) is furnished for each of the three lenses to protect the exposed
optical surfaces when the lens is not in use. The lens caps are
interchangeable since the optical parts of each lens and shutter assembly
are mounted in barrels having the same outside diameter (51 millimeter).
d. Cable release, filters, and lens shades. The cable release (figure
7) supplied with the camera set is flexible and equipped with a plunger and
lock on one end. The other end has a threaded tip which fits the cable
release socket on each of these lens and shutter assemblies. The filter and
shade adapter (figure 1) has a removable retaining ring and an adapter which
fits over each of the three lenses. Either the normal and long lens shade
or the wide angle lens shade can be screwed into the adapter. The filter
and shade adapter will accommodate any of the gelatine (optical glass
mounted) filters supplied as part of the camera set.
e. Cut film holders and film pack adapter. The dark slides of the cut
film holders and the film pack adapter have raised identification dots
(figure 8) for slide identification in the dark. Each cut film holder
accepts two sheets of 4" x 5" sheet film. The film pack adapter accepts one
4" x 5" film pack containing 16 sheets of film.
f. Carrying case, carrying strap, focusing cloth, and tripod case. The
carrying case (figure 3) has compartments to accept all the camera set
components except the tripod (and attached panhead), which is stored in its
own tripod case. The camera component is supported in the center
compartment of the carrying case. The minor components are stored in the
end compartments with the exception of the filters, filter and shade
adapter, and lens shades. These items are stored in the specially fitted
cover of the carrying case. A handle (not shown) on top of the carrying
case and a carrying strap that is attachable to the Drings on the ends of
the carrying case, permit carrying the enclosed equipment off the shoulder
or in the hand. Three hinged fasteners on the carrying case secure the
cover. The tripod case is equipped with snap fasteners to secure the
opening end. A handle on the side of the tripod case facilitates
transporting the tripod.
