Wow your really giving your tubes a good workout Nice and sharp John .
Thanks buddy!
These things are awesome! When paired with my 70-200mm they really give me a nice stand off lenght, while giving the macro feeling and look. They are more difficult with my 50mm 1.8 due to the very close focus, but I will get more used to that as time goes by.
I have a ∑17-35mm EX HSM on order, and I can't wait to give that a shot with the tubes.
