Flahs sync FM3A

[geejee]

Does anybody know the flash synchronisation moment of the FM3A with slow shutter speed? Does the flash fire at the end (rear curtain)?
Thanks for letting me know.
Ps. where can I get the most elaborate and detailed flash technique info on the web?

I don't have FM3A but its easy to check it your self.
1. Set the shutter speed to 1 second.
2. Open the c&era back, look at the curtain. 3. Fire the shuuter(with flash on).
You can see when the flash fires.

Thanks for this tip, it worked fine. Sync is at the start.
