[Konvas] Arri

[Sean McVeigh]

If I recall, the 2C has a butterfly shutter, so makes 2 exposures per 
shaft rotation and the inching knob turns twice per rotation. (I was 
using this as feedback for a speed controller at the time).
The gearing between the motor and the shaft was also not 1:1.  If I 
recall, it was a multiple somewhere on the order of 5 or 7 or so?  This 
is to reduce torque requirement on the motor.  You may also be able to 
drive the camera from the inching knob, but the torques would be much 
higher, and I'd worry about busting gears, although running at 3fps may 
not be too bad.

Cheers,
Sean
