yes Geoff its a well known fault on them , once the a/f motor gets noisy /grindy/ judders it will still take decent photos of static objects etc but you can forget b.i.f etc or fast moving vehicles .. the only way to confirm is to test in real world conditions .. the one I had a few years ago was perfect which obviously clouded my choice . 

  I was also looking at the previous model the 300mm a/f why are you thinking of selling yours
