Sorry, you seem to have been writing a reply while I was editing my post.
Like I wrote in the edited version, what puzzles me is why, with 12mm ext. tube, you are not reaching past 1:3.5, something the lens can do on its own. I will shoot the same anemones with 24mm and 12mm ext. tube, to show the huge difference...

Embarrassing for me, but you are correct, and I am ashamed that I rotated the lens and also racked out the focus with the tube to maximum distance rather than minimum. I will redo this example and re-post the results of the anemone - but there won't be any room for bees this time and I have had less coffee so my process might be more careful this time.
