I've got the feeling that this subject has come up before, however..... I just want to plug my Mecablitz 45CT into my Sony A350. I bought one of those little Chinese adaptors, but the flash fired when I plugged the flash in and then didn't fire when I took the picture.
I saw another advertised and asked the supplier if it would work with my setup. The reply was in the affirmative, so I bought it... but the flash fired when I plugged it in and then didn't fire when I took the picture. Uh huh. I contacted the supplier, who suggested that the adaptor was faulty, and they'd send me a replacement.
It came, and guess, what, the same all over again. So what am I doing wrong, please ?
