Re: External Speedlite Control with 5DMIII

It works for all my three Canon flashguns, 580EX II, 430EX II and 270EX II.  It probably only works on relative new models as others said.

It works now. Ktownbill said to take out the batteries from the camera and flash for a few minutes. That solved the problem!
Thank you for your reply
