Hello all, So I have done a ton of web research trying to find the solution... I have a Mamiya 7ii, I also have a Vivitar Auto 225 flash. Across all the major photo forums I can't seem to come to a conclusion of wether or not the Mamiya 7ii can handle old high voltage flashes. I saw Ken Rockwell and others say you can use any flash under the sun, but I just want to be positive. Ive read a few responses of Vivitar 283's being used, but I hear those are volatile at best and maybe those specific users have a low voltage copy. Does anyone here have any personal experience with a Mamiya 7ii with a flash that is on this list that is classified as 'NO' for EOS compatibility? http://www.botzilla.com/photo/strobeVolts.html Thanks!
