nice Abuttolph, but you need to copy the adress from the image, not from the small icon. Otherwise the image will not show.
here are a few first attempts with ZF 50/1.4 wide open and extension tube 12mm.
Seems like the CY is much better at this, with the Planar the in focus area seams not very sharp - or it is just me.
Cyra - thanks. Actually, I thought that I did copy the address from the image, but apparently it was just the page link. I'll try again below and see if it works.
You are right about the ZF 50 f1.4 being soft wide open. Mine is the same way and I have read about other people who observed the same issue. I also experience focus shift with that lens, especially when trying to focus at minimum or near minimum focus distance.
