Just some questions about this flash (using on a *istD). 1. Why it needs so long time to recharg? Everytime after the flash fires, it needs several seconds to charge before it can fire again. I'm using Sanyo 2300ma rechargeable AA batteries and all flesh-charged. Cannot use continues shoot w/flash :( 2. Set to high-syn flash is the only way I can get speed high than 1/150, no matter what lens I use. Is this right?
I use 2500 rechargeables and it is ready to fire almost instantly. Are you trying to light up a big area and therefore using full discharge with each fire? Maybe this is why, but I don't know as I have never had the problem. I am quite surprised by how quickly my AF360FGZ is ready to fire again.
Yes. The *istD shutter can only provide X-sync for electronic flash up to 1/150 sec. The *istDS reaches 1/180 sec. "High speed" electronic flash is done by strobing the flash repeatedly during the period that the shutter slit is traveling across the focal plane, at th expense of cutting power output quite a bit.
