Digicam Flash Sync.
I have no idea if anyone other than myself wanted to know and what I was continually doubting:
no one seems to know (or agree on) what flash sync speed their digicam (or others) are capable of.
My Owner’s Manual isn’t very clear on the subject, mentioning flash sync only in passing.
*For my EOS SLR film cameras, flash sync is either 1/200th sec. Or 1/250th sec., tied of course to shutter movement.

I’ve posted 29 very static "test" shots at the above site.
The flash sync as you can glean from the Exif data ranges from 1,000th sec *(top row-left) to 1 full second *(bottom row- right).
With the exception of the last five or six shots where you can begin to see the effects of ambient exposure, a feature which culminates in the gaudily overexposed last shot, they are almost undetectably similar.
What did I discover? I learned the FZ20 is uncannily accurate exposure-wise when metering in Shutter priority flash mode.
I also leaned the FZ20 would serve very well as an “event” camera (if you prefer those “Paparazzi” lit shots).
Though it will stop motion at 1,000th sync, at indoors Weddings at that speed the images would not have the preferable ambient-lit background we all have come to expect from quality gear.
In dim venues where flash is permitted, and at 1/200 sec, the FZ20 STOPS ACTION: period.
Outdoors is where the FZ20 comes into its own (in my tests.) There, the FZ20 performs very much like any quality SLR, with ambient exposure and stop action capability.
At outdoor Weddings, set at ISO 80, 1/320th/400th second Shutter priority, the FZ20 is an utterly remarkable performer.
My Shutter priority flash sync “tests” certainly helped me learn something about digicam flash sync, me who had grown up (suffered with) 1/30th second flash sync.
It is up to each individual to discover his/her own flash sync for their specific digicam. Once you’ve discovered what it is, you can shoot with much more confidence.
