600 EX RT not firing on 7D , working fine on other bodies - toni-a - 09-09-2017
Can't find logic reason behind it.
600EX RT is emitting AF assist beam, zooming with the lens on 7D however when it comes to shooting it doesn't fire, I cleaned the contacts on camera and flash, nothing changed, worst 580EX works normally on 7D, 600EX works normally on 750D !!!
Anyone has an idea what's going on ? how to get the flah to fire again ??

If the other flashes are working on the 7D, surely it can't be the custom function disabling flash?..

<p style="margin:0cm;">Which Firmware version has Canon 7d?
<p style="margin:0cm 0cm .0001pt;">If you call canon they will answer you- Please update to the latest firmware. it seems that something is solved in Canon7d FW version 1.0.9

the problem it was working normally on 7D before
tried it zooms with lens and transmits all the info but does not fire, same on 5D and 30D
