Yes, I'm running both flashes at 1/25, and like I said it starts off pretty quick with at least I know 20 or so shots, then it starts dying down to 2 which is soooo frustrating to say the least. I thought of the buffer, but surely it wouldn't be full that quickly could it? I'm leaning more towards the flash, because it seems to me that when I just shoot on continous not using the flash , this doesn't happen, at least not as quickly. If it was writing to the buffer, wouldn't my light on the back of the camera be blinking? It isn't. Also, I always start off with fully charged flash batteries, fresh formatted card and fresh camera battery. But it happens all the time. How long does it take for the flash to recharge and would I still just get 2 flashes off before it stops all over again? I can go out of the room, put the dog out, come back to the camera, and maybe if I'm lucky get 5 shots off then we start back to the 2 again..then wait.then 2, then wait..what a pain...I am using a sandisk 8 gb card that has a 4 on it. A hp 4gb card which I don't see any other number on it and a pny 4gb with a 4 on it..Does that help? The rechargeable batteries are energizers and they are brand new...
