Re: sync speed

Hi Patrick,

You may be right, but I don't bet on that since max sync is given manufacturer is the "safety guideline".

I've tried setting shutter speed beyond my film 7 max sync little (can't remember the exact speed anymore) with studio light. As expected, I got back only half the frame.

Cheers!

Hi Geir,

No, if spec given sync speed of 1/160, any shutter speed greater
than that will result in incomplete exposure unless HSS is enabled.

Not necessarily. Sometimes X sync is a conservative number.

Although my E1 has a reported X sync of 1/180, and the dedicated
flash unit, when communicating to the camera, will not allow
faster than this, unless HSS, I can sync at 1/320 with third party
flashes. You just have to try it with a non TTL or non
communicating flash to see what the real X xync potential is.
