I am now even more confused than before. Setup 5DII, 50mm and tubes.
Issue #1 - how to focus
Do you actual focus using the focus ring or just put it at any setting and move the camera back and forth? It seems that since the DOF is so small, that it does not matter about focussing with the lens but just use the physical placement of the camera.I tried using the focus ring to no avail. I also expect AF does not work.
Issue #2 - F/stop
Does changing the aperature really give more of a DOF that is noticable? It seems to me that since the DOF is so small, it does not really matter. So stick it at f1.4 for light !
Issue #3 - focus stacking
If the answer to #1 above is you can use the focus ring, then I can concieve how to focus stack. However if it requires movement of the camera, how does this work?
Saying all that, I am hooked !! Please help me out so I can focus and get shooting.
