Aaton 35 - Panavision

3.1 CONCEPTThe Aaton magazine has been designed to be instantly installed orremoved, and to be loaded quickly. In order to have a more compactmagazine, both cores (feed and take-up) shift together during filming.The magazine is driven magnetically from two intermediate drivesconnected to the camera motors; two magnetic wheels on the innerside of the camera body couple with two similar wheels on thethroat of the magazine to transport the film. A magnetic drive systemdecreases noise and power consumption, and prevents mechanicalstress during mis-loads.The magazine handles up to 400 ft (122m) loads of 35mm filmstock. 400 ft of film is a little more than 4 running minutes at 24fps3.2 PRESSURE PLATE SYSTEMThe magazine features two pressure plates which are located at the frontof the magazine’s nose. When the loaded magazine is attached to thecamera, these pressure plates provide the precise stabilization of the filmduring exposure and transport.3.2.1 The Gate PlateThe long plate, called the gate plate, is positioned at the camera’sgate. Its main function is to stabilize the film as the claw engages thefilm perf between exposures. Proper tension and functioning of thegate plate contribute to reliable transport and quiet operation.3.2.2 The Picture PlateThe striped pressure plate, called the picture plate, is positioned atthe camera’s aperture opening and is designed to hold the film steadyat the point of exposure. Proper setting and functioning of thepicture plate assures the precise focus of each image.46
