Need some help with using Metz 45 CL-4 with Hasselblad 501CM
I'm having a bit of difficulty and I'm not finding the answers with G searches so I must be using the wrong terms or it's an odd question.
I have a Hasselblad 501CM with 80mm CB lens. The lens has a hole for a flash cord.
I have a Metz 45 CL-4 (non-digital one) flash that I bought for use with both my Hassie and my Nikon F5 (I have the SCA3000 adapter for the Nikon so can use TTL etc).
My question is two fold but Q1 is my most pressing:
1) how do I use this flash with my Hasselblad, given that the 501CM has no metering etc so I can't use TTL (as far as I understand it?)? I have the cord to plug it into the lens, and I have an incident light meter. So if I meter a scene that is EV16 for example and want to add just a little bit of fill-flash to fill in eye sockets or whatever, how do I achieve this my flash without over exposing? How does the flash know how much to pump out with the Hasselblad?
2) When I use this flash with my Nikon F5 with TTL mode, sometimes the Nikon says "H1" (from memory) meaning the flash is going to be too much for the exposure with the given settings (usually aperature priority). With my old flash (the SB800, which was stolen) I used to reduce the power to -1 or -2 or whatever I needed. I can't seem to work out how I achieve this with the Metz?
If anyone knows of a link to a net resource that answers Q1 especially or Q2, please let me know.
