Macro Tube

I got some auto focus macro tubes recently but I have had no chance to actually USE the things with my lovely M.Zuiko 45mm prime until today. This particular shot is only using one of the tubes. The OTHER tube is the subject of course. Note the electronic contact relays. When I get honest with myself, I guess I am really a "macro still life" shooter rather than a "flora/fauna macro" type. Stand by to get bored by lots of close-up dof doodles.
