Has anyone else experienced this? I am occasionally getting this error message 'err 01 camera cannot communicate with lens clean contacts', or words to that effect.It is used with a 300 2.8 and the firmware is ver 1.2.2.Cleaning the contacts had no effect and turning it off and back on again sometimes works.I took the battery out overnight and after firing approx 6o test shots today it only err'd once.Any thoughts would be much appreciated.
Regards Tom
