Hi Shel,
Leaf shutters actual speed depends a lot on the shooting aperture. At
any speed setting, the equivalent speed will increase as the aperture
becomes smaller. As a result, I calibrate my shutters based on my typical
shooting aperture of 16 - 32 for my view optics.
Calumet supplies a nifty shutter speed tester and I carry with me my
conversions based on aperture, calculated based on tests, for those few
times I really open up.
