/p/ros My friend's Pentax ME super claims in the manual a 1/125 flash sync speed. He wants to use it to shoot photos with a flashcube. I have already tested the flash cube adapter with a multimeter.
My understanding from reading the documentation from the flashbulb packaging and a few other places is that with X-sync (instant) only 1/30 or slower will work (because the bulb takes 1/15 sec to reach peak illumination). I know that Focal plane shutter cameras have a max flash sync speed (usually 1/125 for 35mm), but will the camera sync *SLOWER* than that?
I don't have that camera on hand to see if it completes the circuit when other speeds are used.
