Exposure settings help needed

[pzo]

This is embarrassing, since I learned on my father's knee about film speed, ASA of course, f/stops, and shutter speeds. About sixty years ago.

So now I'm wanting to dabble in 16mm, you've may well seen some of my recent posts. My antique store $20 camera is a B&H 200EE. I've not been able to find any instructions on the intertubes. So, here goes:

The case has a dial to set the fps. Gotcha. The "Electric Eye" has a simple twist dial to set film speeds from 10 to 50 vs. fps, 16 to 64. But then the lens has its own f/stop settings from f/1.9 to f/16.

How do these interact? Since any film I anticipate using will be ISO 100, how do I accomplish not overexposing if the fastest film speed option is 50 ASA? Oh, wait, then there's the f/stop setting.

The answer, I suspect, is hidden in plain sight, but I can't see it!

Thanks, Paul

I'm not familiar with that camera but the way many of those old built in exposure meters worked was just reading the light coming through the lens. Usually you would turn the ring on the lens so that the two needles match to get the correct exposure. Since yours only goes to 50 ASA you will need to close down the iris one additional stop for 100 ASA. If the meter says you should be at f/11 then you need go to f/16. That's assuming that the meter is still working properly. You may want to compare it to a good light meter or a light meter app on a smart phone.
