Sweet images -- I especially like #4. (Was that from just a little north of the Flight Deck?) Looks like all of the hardware is working well for you.

here are a couple more w/ the 2x iii + 600mm ii. i know that the last one is not the greatest photo, but it was really special seeing not one, not two, but six of these guys today.
Just received my 2x MkIII today. After seeing these I'm dying for a bit of sunlight. So far it appears 0 MA is pretty close but what's amazing is AF speed even in lousy light.
