Short, Intermediate and Long viewfinder tubes are available. System incorporates an optical magnifier for critical focusing and picture composition, a contrast viewing filter and a light-proof shutter. Wide-range ocular adjustment with marker bezel to note individual settings. A built-in "Panaclear" eyepiece heater ensures mist-free viewing. Adjustable eyepiece leveling link-arm is supplied with every Panahead to keep the eyepiece position constant while tilting. An eyepiece diopter to suit the operator's own eyesight can be provided on request.

35mm Cameras Aaton 35mm Handholdable

This extremely compact camera — 7 kg (15.4 lbs.) with 120 meters (400 feet) of film — is designed for handheld small-camera situations where traditional 35mm cameras would be too bulky or awkward. The film channel is adjustable: Academy, 1.85:1, or Techniscope.

Movement: The movement of the Aaton 35 is a linear stroke, with the in/out movement controlled by a cam coaxial with the claw shaft (U.S. patent no. 3806016). The security provided by the claw's linear pull-down, followed by non-shifting withdrawal from the perforation at the dead point, makes a registration pin system unnecessary — the claw tip itself ensures this function. The vertical steadiness of this pull-down movement is enhanced by the perfect lateral film positioning ensured by a spring-loaded side pressure guide.

Shutter: Reflex mirror shutter, single blade, 180° opening.

Focusing: Through-the-lens viewing and focusing, 6X magnification. Auto erect image. Swiveling viewfinder for perfect eye-to-shoulder distance adjustment.

Lenses: Panavision, Arri PL or Aaton mounted lenses can be installed. The Aaton mount, because it has the shortest flange focal distance of the industry, can receive almost all the best still-photography lenses, like the Leica R, Nikon and Canon-AF.

Motors: A small direct-drive brushless motor (1500 rpm) runs the mechanism. Automatic stop in viewing position. A second motor in the camera body drives the magazine through an independent magnetic clutch. The Aaton battery (12V, 1.8 Ah) fits directly onto the camera body.

Magazine: 400' displacement-type magazine is pre-threaded and allows quick changing. It is automatically locked into position when placed on the camera body and is released by lifting a lever on the motor side of the cam era. The feed and take-up rolls compensate for each other in size, while the shaft of each roll shifts position as the film is exposed. The electronic counter registers in feet and meters.

Video Assist: A small high-resolution CCD video camera attached to the side of the camera only bleeds off 30% of the light from the viewfinder.

Aaton 35-11

Movement: Linear-stroke single claw; self registering (U.S. patent no. 3806016). The vertical steadiness of this movement is enhanced by the perfect lateral film positioning ensured by a spring-loaded side pressure guide. Hair-free gate has air circulation channel to keep hair out.

Shutter: True 180-degree front surface mirror facilitates 60Hz HMI and video monitor roll-bar elimination. Stops in viewing position. May be inched for aperture inspection.

Viewfinder: Reflex from shutter, 6X magnification, auto erect image, interchangeable ground glass. Swiveling viewfinder for perfect eye-to-shoulder distance adjustment.

Lens Mount: Panavision, Arri PL or Nikon interchangeable mounts. 35mm to Super 35 format conversion in five minutes in the field.

Drive: Brushless crystal sync 12V motor for 24,25, and 29.97 or 30 fps. Variable control 6 to 54 fps. Maximum speed with external control is 32 fps. Circuit board and motor may be removed and replaced in two minutes. Slim battery (12V 1.8Ah) fits directly onto the camera body. A second motor in the camera body drives the magazine through an independent magnetic clutch.

Magazines: 122m (400') pre-threaded displacement-type magazine for instant changing. The feed and take-up rolls compensate for each other in size, while the shaft of each roll shifts position as the film is exposed. The electronic counter transmits feet or meters to the camera body.

Features: Digital control display: footage, voltage, speed, ISO, magazine footage, low battery and out-of-sync warnings. The key-code compatible, AatonCode time recording system prints large and rugged time matrixes on the edge of the film, ensuring perfect sync with SMPTE time of audio recorders. 1 ppm TCXO internal clock, initialized with RS232 or SMPTE signals. Negatives from the Aaton 35-11 are fully mixable with Panavision, Moviecam and Arri BL AatonCode-equipped cameras. 46

Accessories: Lightweight wide-format swing-away matte-box; two 4 x 5.6 and one 138mm rotating stages. Also accommodates Panavision mattes. Lightweight and zero-backlash follow-focus system. CCD video assist with manual iris control delivers extremely sharp images.
