Hi, I have a Canon EX 580 Flashgun, perfect condition. Still have the manual, leather case stand.
It’s been used, but I look after my equipment very well. Never had any problems with it. I’m looking for around €370 for the flash.
I also have a Canon ST E2 Speedlite transmitter, never used, with the leather case as well. €150
The transmitter works well when you want to use the flash off camera, I think you can use up to 9 flashguns in 3 groups.
If you want both I can discount a bit on the price. Available to view and test if you want.
