Power Sync mode adjustment with V6II in TX and RF60X in RX (also others flashes with V6II in RX)
I have two topics regarding Power Sync function:
The first topis is setup power level in Power Sync mode:
It fire flash always full power 1/1 regardless setup power level. Is It the correct function? Is there any reason for that? I know that full power 1/1 has longest flash duration which is needed, but I have experimented also with V6(not II version) and was able to fire also 1/2, 1/4, 1/8 and still be able to catch flash with time around 1/640. I think power adjustment should be allowed and it is up to me and my knowledge (knowledge of flash time duration) how I use it.
The second topic is about sinc time adjustment (I use panasonic GH3 body):
So If I setup times up to 1/640 everythink is just fine (flash is fired always full power), full picture is illuminated.
When time is shorted than 1/640, up to 1/4000 the picture has dark band on the top of the picture. Sinc time adjustment setup on 0 (on the left of the bar). (1/640 just a little bit on the top, 1/4000 already one third of the top picture is black). According your manual I should turn the dial to the right to achieve better results, but the situation is even worst (corection setup to 15 (middle position) time 1/4000 and picture is almost completely black). So I assume that manual is written opposite way, but most importantly I can not setup my shutter beyond 1/640 (because I can not set up less Sinc time adjustment than 0)
My question is: Did I miss something? Is Sinc time 0 the minumum time delay, what HW is capable? I suppose I need it a little bit faster to achieve time beyond 1/640 and full illumination of pictures.
