HI, I have a 24-85mm that was converted in 2010. Serial 12715500. It has always worked faultlessly on my 5DII right up until a few days ago. I sold it and the buyer has tried it on a 1-DX and 1-DIV and says that it won't focus. The green focus light flickers but the lens won't move. Manual focus is fine and gets focus confirmation. It communicates with his camera bodies otherwise. I checked it on my 5DII right before I shipped it and it worked fine.

Is there a need for a firmware update to work with new canon bodies? Or, do I need to send it in to be checked?


Thanks!

Probably AF have failed. That was exactly what happened to mine but have since been fixed and returned from Conurus. Better send in for repairs.
