Hi Zach, This line from the JK106 manual (http://www.filmlabs.org/docs/JK106.pdf) suggests that the default exposure may be 0.175 or 1/6th second:
> (EXP TIME) - EXPOSURE TIME > Selects the desired exposure time in increments of 0.1 seconds. The > minimum open-shutter exposure time of 0.175 > (for Bolex H 16 Rex. 120 rpm motor = 1/6 of the second exposure time ) is > automatically accounted for. "0" exposure time = this value. > In anycase, I've never relied on any mathematical calculation for exposure using a JK, just lots of bracketing exposure tests.
