Re: How did you stack the EF 2x III and EF 1.4x III

Yes, with the control ring. All 8 pins seem to have independent springs, and the force seems comparable to Canon lenses (but I didn't attempt to measure this). The adjacent pins didn't move.

OK - then it better than mine. As it seems also easier to mod (less material to remove), I'll have to get one of those. Disassembly is likely not an option, though.

I also have the Commlite CM-EF-EOS R, but I can't find it at the moment. If I locate it, I'll check it and report back later.

That would be nice - thanks!
