View Full Version : Shutter question

I have an Alphax 4 and wondered if setting the speed ring between marked speeds say 1/5 and /10th would give an intermediate speed or whether there is a set speed only relative to each indicated marked speed?

Yes, it should since the cam is a smooth continuous curve.

Confirming what Jon said, the Betax shutters do offer intermediate speeds, indicated by the dot between each number.

Thanks for your replies. Very unscientifically to my ear that seems to be the case. This could at times be quite handy if I can get reasonable accuracy.

In-between speeds are rather silly with large shutters unless you have done shutter speed tests. They can be 1/2 stop to a full a stop from the dial display.

If you have an old 35mm body with mechanical Copal shutter like a Nikon FM you would be surprised how close you can come to 1/8th, 1/4, 1/2 second by listening to the Nikon a few times and matching the delay simply with your ear, irregardless of the numbers on the Alphax.

I know this is not what the OP asked, but just for the record, the Copal shutters do not work this way. Do not use intermediate shutter speeds on Copal shutters.
