View Full Version : About compur shutter

how many different generations are there?
I read Kerry's website about copal shutter on Fuji lens, there are sort of 3 generations of copal shutters.
Anyone knows about how many generations of compur shutters (let's say post wwII)?
It seems that the latest is the all black shutter with B but without T. Does anyone have a time line for the different generation of compur shutters?

Songyun, P-H Pont presents one in his book Les Chiffres Cles. There's too much to type, it looks a little incomplete, and I'm not sure it will address your question.

You can buy a copy from FNAC. My copy is the 3d edition, when I bought it from Atlantida FNAC was still selling the 2nd, so make sure you get the latest. If the 4th edition is out, please tell us.

Of course. But there isn't much text and the dates and numbers usually speak for themselves.
