About a week ago I received a set of Kenko AF Extension tubes that I had ordered off Ebay. I have a set of manual extension tubes that I have used with mixed results. The reason the results are mixed is my Sony A37 does not support Image Stabilization on my Minolta manual lenses. With the AF enabled tubes I have been able to get some images I am happy with. Here is a cropped pic that I used the AF extension tubes with.Post shot editing was done with On1 Photo and Corel PaintShop Pro X7.
