My flash fires sometimes and sometimes not. Both on camera and even when I press the red ligt and the flash is not connected to the camera. Same with new and old batteries and whatever I do. The flash seems to think it was fired when it is not cause it is a flashsign in the camera when the picture is taken. I have EOS 5D mk3. What could be the problem?
There is simply not enough info in your post to make heads or tails out of your problem(s). When you have any problem, the first thing you'd want to do is to narrow down the cause..eliminating possible cause and hopefully you will find the real cause.
The first thing I would do is to check the flash manual and find out how to reset the flash to factory default. There are a lot of settings that could prevent the flash from doing what you expect it to.
If that doesn't solve the problem, I'd start to clean the battery contacts on the flash, then the contacts on the flash foot
on the flash then the contacts on the camera...
