Woohoo!! All fixed!!

It was the entire focus assembly that was loose. Once I got the
lens apart I found that as normal there were three screws with
shrouds around that slide in helical tracks, which slides the focus
mechanism back and forth. Well, two of the three were totally out,
so the assembly was hanging on one screw. When I took the circuit
boards etc out which were holding it up, it just about fell apart.

I refitted the two that were out, and tightened the third. This was
all a looooooong way inside the lens!

All back together now, and the artificial star looks good. Also the
autofocus performance is WAY better than it was before!

Thanks for your assistance.

The weather's not looking good for testing it out tonight though......
