Thank you for the help. Sounds like something like the digisix would work.
As a follow-up, do the Petri and Leica shoe-mounted meters, or any "vintage" ones I haven't seen, meter enough for 800 or 1600 iso at 1/30 at f2? Basically, I want a meter I can take with me to the bar or campfire, and shoot in low ambient light. Age really is more of a plus than a minus, as long as it can do the job. I'd prefer something smaller than a pack of cigarettes. Shoe mount isn't a requirement, but certainly my first choice.
Is this a realistic goal, exluding the gossen digisix and sekonic L208? I'm not cheap, I'm living hand to mouth -) so if there is some old GE meter that would work, please share.
