During wedding receptions, my Sunpak 383s fire very inconsistently. Every time I press the test button with the Cybersyncs, they fire every time. When I press the shutter button, they don't fire. ...
I have 5d mark ii and 580EX ii, the flash menu was available on the cam and used it for few days. Lately I can't find the menu anymore, I've tried several things and no positive results.
