Did some star testing on my ED82 and ED50 with a led light and foil with pin hole approx 25m away
ED50 tested better with easily visible perfectly round defocused rings inside and outside focus.
Pictures show them as oval rings for some reason.
ED82 had round defocused rings, inside focus had more easily distinguishable rings than outside.
