Bolex Product Codes:- 210.040 Camera Body supplied with power grip, Varta Deac battery and battery charger without TV Frame in viewfinder, 210.041 As previous but with TV frame in the viewfinder.
Bolex Released the H16 EBM camera in 1971. It was the first camera to contain within the camera body itself, all the electronics and the motor that you previously had to attach to the side of spring drive cameras if you wanted them to be driven by motor instead of using the internal spring.
The Bolex EBM camera has inside of it all the circuitry and mechanisms of an external ESM motor. Because it is the first camera Bolex produced which had no internal spring drive it therefore is the first ever not to have a winding handle on the side.
The EBM was primarily designed for shooting sync sound films which it can do using the old sync pulse system of keeping sync by fogging a frame of film at the start of a take then simultaneously put a beep on the soundtrack and then continuously write the motors speed fluctuations to tape. Or the crystal sync way of regulating the motor and making sure it operates at 100Hz. See 16mm external motors and sync sound equipment section for more information.

Other radical feature changes are:-
1 No variable shutter, the EBM has a fixed open shutter angle of 170 degrees.
2 No Frame counter or audible footage counter although it still does have
the visible footage counter. 3 No screw threads to mount any external
electric drive motors such as for time-lapse. 4 It has a 1:1 Drive shaft
but this can't be used because there is no mounting holes for attaching
a motor on the camera body (as discussed above) but also the internal
electric motors would have to be internally disconnected. 5 Still no built
in exposure meter so you will need to buy Bolex bayonet lenses with built
in exposure meters on them such as the POE or buy a light meter when using
Non metered lenses. 6 Has a bigger metal carrying handle as well as the
carrying strap. 7 It needs a 12V 1.2Ah power source to function which
can be either supplied by the power handgrip, Power Base or external power.
8 Filming may stop with the shutter open fogging a frame of film and give
a flash frame.
