Marque : "Super Panatar Anamorphotic Attachment A 7385 Manufactured by Panavision Incorporated Los Angeles, California Made in U.S.A. - Pat. applied for".

"The Panavision effect in projection is created by an auxiliary lens attachment, named the Super Panatar, which is completely compatible with all existing motion picture equipment (conventional of anamorphotic) and it means this to you as as user : 1. Highest definition - sharpest resolution. 2. Ultimate in color rendition - pure white light. 3. Elimination of distortion due to curved screens. 4. Greatest light transmission. 5 Proper "squeeze" with all focal lenght lenses. 6. Quickly adjustable for any squeeze ratio from 2.66 to 1.0 down. 7. Adaptable to any standard projector. 8. Accomodates all standardr projector lenses. 9. All glass surfaces easily cleaned. 10. Can be mounted or dispounted in fixe seconds. 11 Reasonably priced. [...] The Super Panatar is mounted on the face of the projector head and independent of the projector's lens. Panavision Inc. provides an aceptance bracket for the Super Panatar which will adapt it to standard models of the following projectors : Simple, Motiograph, Century, RCA, Brenkert, and others. In most cases, the mounting of the Super Panatar will require nothing more than drilling two holes in the face of the projector head. In certain installations, modifications will be necessary such as removing the front shutter and shifting the position of the focusing knob. Only in the case of extremely old equipment may it prove necessary to make extensive alterations or to replace the equipment entirely. [...] Concerning the objetive lens of the projector, two important factors must be keep in mind. First, that in most installations a much larger screen area will have to be illuminated by the projector. Therefore, in order to maintain proper screen brilliance and definition, it is highly advisable to use only fast, precision-ground, coated objective lenses. In the final analysis, the performance of the Super Panatar can be no better thant that of the objective lens with which it is used. The second point is in regard to the focal length of the objective lens. By reffering to the chart, it will be seen that most installations will require a longer focal lenght lens than those used for conventional 1.33 to 1.0 projection. A brief mention is made at this point regarding an extremely useful feature of the Super Panatar. It may be found that an objective lens of the exact focal lenght necessary to fill the screen is not obtainable. However, tests have shown that by adjusting the prisms of the Super Panatar, the projected image can be "squeezed" or "unsqueezed" by as much as 5 % without noticeable distortion. This makes it possible for the projectionnist to obtain just the right amount of bleed-off on the screen edges, assuming that is objective lens brings him with proper range" (Instruction manual The Super Panatar, A product of Panavision Incorporated, Hollywood, Panavision, s.d.).
