Thanks Clint. One serious guy among all you balls-crazy funny boyz...
I'll take a look at the focus. I don't see any signs of impact or previous
surgery... the ball race I opened was the one at the filter-ring end of the
lens. I think I got it about 95 0.000000ill before, and I now have four more to
add in (if I dare).
