Looking at the copal press-No1 and No 0 shutters for a project and noticed that they are restricted to 125 as the fastest speed, is anyone using these shutters and finding this to be a problem in real world shooting?
Does anyone know the physical dimensions of a Copal Press-No 0 shutter and in particular the overall diameter of the shutter body?
What determines wide open spec of a lens, ie some are 4.7 or 5.6 and go way out to F8 or 9, is it just the design/construction and shape of elements etc or is it also the shutter it's mounted in?
Would it be possible to remount Kodak 203mm front and rear elements in a Copal No 0 shutter?
Thanks all,
Chris.
