This is another problem I have when trying to make use of every piece of my 35mm equipment to save cost on LF. My 210mm lens has a PC connector but 540EZ doesn' t. I guess I need some kind of adapter in order to trigger this flash. Adorama s ells cheap($10)'PC to hotshoe' and 'hotshoe to PC' adapter with no description. I guess one of them may be the right thing for me but don't know which. Are ther e other cheap solutions?
