The thread so far...

To summarise up to this point:

  • The effect noted by the OP is a genuine observation, and not the result of mis-focus or one of several other suggested causes
  • We're still not sure what is going on
  • The "f-stop blues", to borrow Steen Bay's wonderful phrase, is one plausible hypothesis.
