Function

The Arriflex 35BL was the first silent 35mm camera (BL stands for blimped).^{[citation needed]} It uses a fixed butterfly reflex shutter, which gave the cinematographer an exact representation of the recorded frame. It recorded up to 100 frames per second, which was revolutionary in documenting sporting events. It uses a dual registration pin system. It also has an odometer-styled analogue footage counter. The camera uses both 400 feet (120 m) and 1,200 feet (370 m) magazines.

History

The development of the 35BL began in 1966, since there was no handholdable, silent, reflex 35 mm camera at that time. The release of this camera, together with the Panaflex Lightweight released in 1975, changed the filmmaking process profoundly and made big camera setups like the Mitchell BNCR obsolete.^[1] The Arriflex 35BL was released just in time to document the 1972 Summer Olympics, in Arri's hometown Munich. This led to a huge boost in popularity of this camera. It was also one of Arri's longest running product lines, being produced from 1972 until 1990, when the Arriflex 535 replaced it.
