THE FIRST IMAGES on the first two rows are the 85 1.8 without tubes. I added the tubes as indicated by the file names for the rest of each series. Starting with the flower pictures, I only used the 12mm but shot two each, one at closest focusing (about 14 inches) and one at fartherest focusing distance (30 inches). these were also shot at 1.8 as I wanted to see the focus plane. I will add more later as I try out the other combinations of the two tubes.
