What flash system (if any) do you use?? I know Metz & Quantum are compatible flashes.
I use both the Metz 54, 76 and Quantum t5D. They both have advantages and disadvantages. I think the light from the quantum is a bit better. I am going to sell my quantum flashes though because of the requirement for the outside battery (e.g. turbo 2x2) requirement.
So are you going to stick to the Metz? Did you need to get the Hasselblad Flash Adapter SCA3902?
