Scott Wallack asked me if I used my 2X on my 800 for my Moon shot this morning. Answer no. (Why? With so much Sahara dirt in the atmosphere) but... reminds me of my Hillbilly Lens Test I did the Weekend my big lens came into Fort Worth Camera. (Canons biggest in production) I call this a Hillbilly lens test because it is not really scientific. For example, what if I did not have a perfect focus for each lens? And how about a bit of cloud cover changing the exposure? And how about one of my lenses having sun screen on the outer glass? Etc... But this is still a useful test. If you Google Brian Luenser and Hillbilly, you will see I have done other Hillbilly tests. forum.dallasmetropolis/showthread.php/102846-Hillbilly-Lens-Test-(Adding-my-new-Canon-800mm-5-6L-IS-to-my-kit)
