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

<p style="margin:0cm 0cm .0001pt;">PS: It happens similar to my 50d and 430EX MK2 flash. Solved after update. it was clearly mentioned in release notes.
