Hello, I have the FB-tube for a few days and it works very well. I would like to try it now with a macro extension tube. Where is the extension tube used? Between lens and FB-tube or between camera and FB-tube? Thank you!

There shouldn't be any difference, the tube should work both if mounted between the lens and the extension tube, or between the camera and the extension tube. The main point is that extension tubes should have electrical contacts.

My Canon lenses tend to prefer the extension tube fitted to the camera then the FB tube. Tend to have problems communicating the other way.
