I guess I was just trying to point out not all early H16 reflex cameras have a 130 degree shutter. I should have stopped there, sorry for any misinformation:) Thanks Richard, that was useful info and website.

Actually, I believe the early h16 reflex (the pre rexs' without the variable shutter) do have a 143 degree shutter. I have one, circa 1957, and have always used the 143 or 1/60 with rx lenses. When using non rx lens I add the light loss correction, ~1/80.
