i have a quantum, what is the problem?
did you get the correct cord?
charge the quantum, it is explained in paper.
plug quantum, into sb800, while quantum and sb800 are off.
then turn on quantum first, then sb800
you will be hooked up, you still need batteries in sb800, to run the data.
quantum is for flash only.
do not shoot bursts of more than 2 or 3, you will burn our flash.
quantum is great when you need to have a large amount of, shots using flash.
people who use it to burst, will be unhappy, it will blow your flash.
quantum is a power supply, it gives long use and quicker recycling, but you still need to use some intelligence.
enjoy, i think it is great.
