Other 65 mm cameras had noise production of up to 50 dBA, which made sound recording impossible.
[1] The final Arri 765 uses four crystal sync motors, two in the body and two in the magazine, due to the wider and thus heavier film stock.
[2] Films shot on the Arri 765 include Shutter Island (2010), Gravity (2013) and The Hateful Eight (2015).
The camera can record between 2 and 100 fps, the motors can run both in forward and reverse mode.
Due to its compact build, it is adaptable to most 35 mm filmmaking workflows.
