hi how many full power pops you get from the
200 flashes at 300J and 100 at 600J according to the seller.
does anybody know the t.1 flash duration at full power of these unit ??
I friend bought a 3 set of 600ADs with power packs we’ve used them on location during wedding shoots and tomorrow night i am going to use them for group shots at an engagement party, so far they work well and very good at the price
I have 300 and 600J flash and it dit not freeze action like I want to…
My speedlight is more efficient for freezing action than this more powerfull flashes. I don’t know why …
Speedlights are, by design, much quicker than more powerful flashes. Only since quite recently can you get monolights with fast flash durations.
The flash duration is long … I start to lose flash power with a shutter speed faster than 1/80th. At full sync speed of a 70D (1/250th) I’ve lost about 2 stops. This is in the dark room with no ambient light, f8, ISO 100 etc.
