And the 80 1.4 Summilux! All these used wide open, also stopped down to f 8.0! And it was Ok to manually focus at f 8.0. I even had a go with the 280 2.8 wide open then added the 1.4 extender to see how it would look, it's kind of awesome! ;-) Because now the 400 becomes 640 f4.0! I didn't have time to try the 280 with the 2X attached @ 560 .... 896mm! :-) The really big test to come is the 280 + 1.4 extender + 2X extender making it an 800 f 8.0 to become a 1280 f 8.0 mounted on the Canon 20D !!!!!! :-) If we have some good weather over the next few days I'm going to try the "1280 version! ;-) Will let you know how they look. ted
