Hi all. One week ago I purchased a Mamiya 7 II with 65 f4 and 150 f4.5, for to replace Mamiya 6 MF that i bought four weeks ago, problem with the locked film advance lever. Do you know what flash work with the 7II, I have a Metz 32 MZ3 and don't work with this one. I have a Canon 580 EX but I don't know if is good. Thanks in advance. Sorry for my bad English.
