Hello all!

Having picked up a set of Spiratone extension tubes, I decided to tool around with them today. I've attached a few photos taken with the SMC-M 28mm 3.5 and the 20mm extension tube. What amazed me (as can be seen in the rock and crop-copy) is how beautifully the M preserved the detail and the color. Very little color adjustment was made in Lightroom to these photos.

Yes nice detail in the areas that are sharp. With a 28mm you start out with some good Depth of Field (DoF), but the extension tube reduces this in an extreme close-up/macro. I would guess you shot this near wide open (f3.5). You needed to be at f8 or 11 to get better DoF, which would the blossom, multiple blossoms and fungi images. Keep showing us your work!!
