or free-form objects, such as most titles and cartoons, can be grossly distorted by the SUPER PANATAR without objectionable effects. However, it must be kept in mind that films which contain objects whose proportions are easily identified MUST BE PROJECTED ONLY AT THE ASPECT RATIO FOR WHICH THEY WERE INTENDED! You cannot project a conventional 1.33 to 1.0 print of a typical dramatic motion picture through the SUPER PANATAR (or any other anamorphotic lens) when it is adjusted for 2.66 to 1'.0 projection . . . the distortion will be intolerable.
FOCUSING THE PROJECTOR IN CONJUNCTION WITH
It must be well understood that the aspect ratio of any anamorphotic lens varies according to the focal length of the lens on the projector. In other words, an anamorphotic lens will project a slightly wider picture when used with a 2 3 /4" projection lens, than when it is used with a 6" projection lens. For this reason, the SUPER PANATAR is not supplied with a complete aspect ratio scale, and it is necessary for the projectionist to indicate proper index marks on the aspect ratio dial.
Four indices are provided next to the edge of the aspect ratio dial. These marks make it possible for the projectionist to lay out a "vernier-type" aspect ratio scale. The following procedure should be used: adjust the lens (by projecting through it) for 2.66 to 1.0 and make a mark on the aspect ratio dial opposite the fourth index mark. The lens may now be adjusted for three other aspect ratios (probably 2.0, 1.75, 1.33) and the other three index marks utilized. It will be found that this system spreads the scale out considerably and makes it easier to read than if only one index were used.
THE SUPER PANATAR
The SUPER PANATAR is a fixed focus supplementary lens and does not require focusing. The projector lens should be focused in the normal manner. In theaters with a projection throw of 70 feet or less, a "short throw" attachment must be used with the SUPER PANATAR. These attachments are available from your dealer at a nominal cost.
MAINTENANCE OF THE SUPER PANATAR
If it ever appears necessary to clean the surface of the prisms, the lens may be dismantled as follows: Remove the screws which secure the lens housing to the chassis, and very carefully remove the chassis from the housing. The prisms are secured to the chassis and they must not be moved. The prisms may now be readily cleaned. Reassemble in reverse sequence.
For service other than that described above, consult your regional dealer.
