A speedlight will take up to 5 seconds to recharge from zero to full, so if you fire off a full-power shot you'll have to wait five seconds. Two and a half seconds for half power, about one second for a quarter power, half a second for 1/8th etc. But most speedlights will fire without being fully charged, so you can get 8 x 1/8 shots in a row easily.
Yeah the Oly doesn't have the same problem. Lucky! =)
That makes much more sense. Didn't realize subsequent flashes weren't full power. Hmm...should try using the flash with burst on my DSLR's (Pentax) and see how it goes...not that my ancient Pentax's have very fast burst...Still, would be good to learn how to properly use a flash.
Well, to be clear, a flash won't fire if you ask it to do 1/2 and it's at 1/4 charge, but if it's at 1/4 and you want 1/16 it usually will. not always though! I had a Nissin that wouldn't do anything if it wasn't fully charged.That makes much more sense. Didn't realize subsequent flashes weren't full power.

Once again, thanks for the info. Greatly appreciated
Yeah, 8mpix isn't really good enough. I did consider this though, and I figure the big problem is syncing the lights with the shutter. I can see the two drifting out of sync pretty easily.
I reckon I will give it a try though, set the camera up at full speed, remote-triggered at the same time as the lights, everything firing at 8Hz.
Or borrow dad's Oly.
It's better than Monty Python.
And to be clear as mud. It depends!Well, to be clear, a flash won't fire if you ask it to do 1/2 and it's at 1/4 charge, but if it's at 1/4 and you want 1/16 it usually will. not always though!That makes much more sense.

Some flashes (with CPU communication to the body) will only fire (or let you make a shutter activation) if they have charged enough to allow the requisite power to be delivered. Think of it as a ' correct flash power priority' mode
Other flashes will let you take a shot regardless, even if the capacitor hasn't reached full charge, the assumption being an underexposed shot is better than no shot at all. Think of it as 'shutter priority' mode.
I have a feeling that some flashes let you set this priority mode (higher end Canon models?)
FWIW. This has been a very useful thread. Its the kind of thing I do very occasionally, and I can imaging thinking "I'll try using the MFT gear today instead of the Nikons...." and getting caught out as well. One would assume that this would just work. Annoying.
I actually had to check it myself. Tried it on a GH3 and put the drive mode dial into continuous. The flash does actually fire .... but only once, as the camera disables the continuous drive (it can't stop you selecting it as its a physical knob on the GH3/4). It does therefore seem to be a deliberate operating decision forced upon you by Panasonic.
I tried it with an FL50 and also a 3rd party radio trigger. Same result.
Bugger.
A test session, fine (but did you say so?). Regardless of that, you set up the camera lights, etc., and you fire off a test frame or three just to make sure you remembered to plug everything in, the wireless triggers are working, etc.
Fine, and I have been warned, and appreciate that.
To the people who matter, yes. =)
Was it ?
You're not even a reader apparently. The post immediately preceding yours:
Last I checked this was not CareerReview.com. I'm sure you thought you were being helpful, but you're basically making ad-hominem attacks instead of contributing to the conversation.
Why? You'd have just complained that my unprofessional studio uses the wrong shade of white paint on the non-standard curve of the cyc-wall.
The Cactus RF60 light has a delay feature for situations like this. I set the camera up and increased the time by 5ms over and over until I saw the flash in the photo. Then I stepped it back 1ms at a time until I had the lowest number possible.I'm not countering your facts (really) and I know you are saying it's an approximate but how are you measuring such lag?Also the shutter lag using a remote is ~67ms.
