Question about M3 shutter speed

[Banky]

Do you have any accurate way of using the M3 dual stroke, since the shutter speed on the M3 dual stroke has the odd number, but not even number?

1. buy an old exposure meter with the 'old' speeds-Weston II is good if it works
2. estimate the correct f-stop: speeds in old cameras aren't always what they're supposed to be so you can't count on accuracy

What do you mean by the odd numbers? Doesn't it have the 15/30/60/125/250, etc?

The old progression in 1-2-5-10-25-50-100-200-500-1000 as opposed to 1-2-4-8-15-30-60-125-250-500-1000...

Colyn has it right: the early M3's had the 'old' speeds.

Just load TriX and wing it. There is enough latitude in the film, technical inaccuracy of the shutter and meter...... close is good enough.

Ah, that's cool. Learn something new every day.
