Hi csjoe,

I know its a long shot but have you tried resetting the camera

menu spanner, clear settings - clear all camera settings.

Good luck.

yes, try that. Also, as mentioned, something with the contacts. try cleaning the contacts. Try mounting the lens several times in a row. on off on off...

PS: was there any firmware update?  Or try to use magic lantern?
