Girlfriend and I are diving in Bonaire- the flash on her E-PL5 starts to flash intermittently then not at all- I put the FL-LM1 flash module from my E-PL5 on her camera and the problem resolved. I put the flash back on my camera and on Friday my flash unit fails the same way. Any similar experiences with this failure? The units are easily replaceable but at $50 a pop I'm not pleased about doing it once let alone every dive trip. Any help or suggestions is appreciated. Contacted Olympus and no reply.
