Canon 5d mark III does not recognize the Canon Speedlite 580EX II is connected

[PabloZee]

When I choose External Speedlite control/ Flash function settings on the 5D.

I get a dialogue that says

This menu cannot be displayed. Incompatible flash or flash's power is turned off.

Flash is on. If I take a photo, flash fire's. Pictures are ALWAYS over exposed when using the flash.

Does the 580EX II work with the 5D Mark III?

Good to hear PabloZee 🙂

We wish to know about your experiences installing/using Magic Lantern. Particularly, how practical it is in terms of sharply reduced footage time, and other issues you have encountered. Thanks,

Try taking some rubbing alchohol to the connections of the flash and the hotshoe mount. That did the trick for me.

Well said.  I paid top dollar for both my EF 24-70 f.2.8 lens and the Speedlite 580EX II. Worked fine for a long time and recently, the lens went nuts and would only focus on the right side of the frame and the flash overexposes ALL the time.  After many years with Nikon, I went with Canon because their support was known to be hands on.  It does not seem to be the case anymore and I am seriously considering going back to Nikon or perhaps Sony. Shame
