I say dumb because I can mount it and check, but I am on a buisness trip for 10-days and the camera and flash are back home.
I have a new (to me-used) 60D and my original Canon 580EX flash unit (NOT the newer EX-II).
The 60D can control a hotshoe-mounted flash from the 3" screen using the camera controls. This would be a boon to me as I use reading glasses and the camera screen is much better than the flash screen to see.
I have seen conflicting reports, some say it will only control the newer 580EX-II flash units or later, some say it will control the 580EX Mark I older model like I have.
Anyone know? It's becoming increasingly harder to find resources on the old 580EX it's all about the 580EX-II now. If nobody knows I'll just play with the gear when I get home.
Thanks!
