camera with the lens base and camera mounted together.

Todd-AO Camera Lenses
The Todd-AO Camera Lenses are of a radically new type and they are a basic
element in the Todd-AO Process. Because of their design, there is no simple
meaning to a focal length designation. Therefore, they are identified by the
horizontal angular field covered by them when used on the Todd-AO Camera. At
present, there is a compliment of four such lenses accompanying a camera.
These four are the 128° or "Bugeye", 64°, 48°, and 37°. Because angular
coverage is an unfamiliar designation, it was felt by some people in the
industry that a simple letter designation in addition to the angular field
might be helpful. Therefore, the 128° is called the "A" lens, the 64° the
"C" lens, the 48° the "D" lens, and the 37° the "E" lens. It will be noted
that no "B" lens is listed. This was omitted because it was felt that at
some future date a fifth lens between 128° and 64° might be desirable.

Todd-AO 64° f/2.2 Camera Lens.
Todd-AO 64° Camera Lens (Cat. #06)
Because of its large size, the 128° lens has a different mounting than the
other three. This can be seen in the "Bugeye" Camera illustrations in
Volume I of this catalog. The remaining three lenses are mounted by a simple
Bayonet type of lock and are termed the "Bayonet Lenses". All of these
Bayonet Lenses are interchangeable.
All Todd-AO Camera Lenses are coated to increase light transmission and
reduce flare.

Todd-AO Wide-angle Follow Finders

64° Finder Adaptor (Cat. #16)
These erect image Follow Finders are fitted with three adaptors which cover
the complete range of angular coverage of the Todd-AO Lenses. The 37°-48°
Finder Adaptor is the equivalent of the widest angle standard finder adaptor
available today. The 64° Finder Adaptor converts the finder for use with the
64° Todd-AO lens. The 128° Finder Adaptor covers the full angular field of
the 128° "Bugeye" Lens with enough field to spare so that a small portion of
the scene appears outside of the matte bars when they are set for 128°. This
gives the operator advance warning of objects coming into the camera field.

The matte bar adjusting knobs are engraved for the four Todd-AO Lenses and
provision is made for adjusting the matte bars independently and locking
them in any relative position for exact framing.
The Finders are equipped with cam followers for the parallax correcting cams
on the Bayonet Blimp.

Todd-AO Camera Magazines

65mm Todd-AO Camera Magazine (Cat. #13)
The Camera Magazines are designed to handle 65mm film. The film core
spindles are fitted with a keyway for key-type cores and with a re- moveable
key for keyway cores. The earlier magazines have plain bearing throat
rollers while the newer ones have ball-bearing throat rollers. The inside
throat rollers in all magazines have "buried" flanges to help prevent edge
shaving and run-off due to poorly spooled film. These flanges are "buried"
so as to prevent the film from ever running up on the flanges if a slack
loop should form. Magazine chamber covers are of the conventional screw
type.

Todd-AO Camera Magazines (Cat. #13)
Large pulleys provide for using larger than normal take-up spool. These
pulleys are protected from damage by blocks around the edges of the magazine
at its inherent strong points. Thus the magazine may be laid flat on a table
without fear of damage to the pulleys or shafts.
