Very interesting thread. I've been thinking of buying some Kenko extension tubes, does anyone know what their internal opening is lined/painted with?

I don't have any personal experiences with the Kenko tubes. But when I google them and ask for pictures, it looks like they don't have the shape/surface on the inside designed to reduce reflections, as the Fotga tubes do. A bit surprising in view of the fact that they are more expensive.

Perhaps someone who knows more about the Kenko tubes can verify (or reject) my somewhat provisional observation.
