Re: Macro add-ons for the Canon 100 2.8(non-IS)

I use the Opteka extension tubes with the Canon 100mm f/2.8 non-L.

You DO want electronic coupling in your extension tubes if you're going to use a Canon lens for macro photography. The reason is not auto-focus (because you'll likely want to manual focus anyway for any macro setup) but because Canon's lenses have electronically controlled aperture, and if you don't have this electronic coupling you will not be able to stop down the lens. f/2.8 is more often too shallow of a DOF for most macro work of still subjects.
