User manual ARRI 16 BL

[. . . ] Constructions and Design The ARRIFLEX 16 BL is a noiseless 16 mm mirror reflex newsreel camera with electric drive. In order to maintain the excellent technical features of the proven ARRIFLEX models 16 St and 16 M (such as the precision film registration pin, forward and reverse operation, tachnometer, footage indicator interchangeable motors, mirror reflex system, etc. ), achieve a low noise level and avoid excess weight, this new camera has been built with a fully sound-proofed construction in which all, components which produce or conduct noise have been insulated within or upon the camera body. This applies to the camera mechanism complete with the film transport system, the interchangeable motors, the lens, the viewfinder system, and the magazines. This construction makes the ARRIFLEX 16 BL an extremely versatile, noiseless, and relatively lightweight newsreel camera which con be used equally well whether mounted upon a tripod or hand-held with or without a shoulder support. [. . . ] The glass element built into the camera door Is part of the finder system, For occasional cleaning this element and Its mount can be screwed out of the inside of the camera door, Replace carefully after cleaning. In the course of redesigning the quick-change finder mounting, which, as already ready mentioned forms an integral unit with the camera door lock, the door lock was also improved, In place of the former knurled locking ring, a knurled locking lug now makes opening the camera -door easier.

This quick-changing magazine with built-in feed and take-up mechanism holds 400 ft. If black-and-white film is used, film rolls with a total length of 500 ft. In addition, this magazine is equipped to take 100 ft, (30 m) and 200 ft (60 m) daylight-loading reels. 1629), which is unblimped and should therefore be used in cases where long takes are expected and low noise level operation is not called for. The feed and take-up reels of this magazine are arranged side-by-side to make it relatively light and compact. In order to reduce noise, metal gears have been matched with plastic ones. Magazine Throat The feed and take-up sprockets in the throat of the magazine guarantee that the film Ioop in the interior of the camera remains at a constant length whether the camera is in forward or reverse drive. The magazine throat has a labyrinth-type film channel which acts as a light trap to keep out stray light. The dovetail in the magazine housing serves to attach the magazine to the camera. Film supply indicator Located on the rear side of the magazine, the film supply indicator refers to black and-white film. lf colour film is used, the film supply can be estimated by subtracting 10% from the footage shown. The indicator is available with scales in metres or feet; these are interchangeable. The film must be wound with the emulsion side in on type T plastic cores. All international standard film cores with an inner diameter of 1" with slot or lug, and an external diameter of 2" may be used, The maximum capacity of 400 ft. (120 m) given by the manufacturer should never be exceeded, except for the above-mentioned case where 500 ft. (150 m) of black-and-white film is used in the 400 ft, (120 m) magazine. It is advisable to practice the operation of the magazines in daylight with blank film. Later handling in the darkroom or changing bag will then prove easier, 14 A.
