I have an old synchro compur shutter that I want to play with (had 150 lens attached) and just received a set of lens cells to put in to the shutter (Also 150mm).
In my estimations the aperture scale should be calibrated correctly as the focal length has not changed, but the full open aperture is faster (Was f9 now f5.6). So how do I open up the aperture to the correct diameter?
