Just heard a knock on the door a couple of minutes ago. The mailman delivered a small box containing... the extension ring! Yehey!!! That was fast. Some guys are really awesome on ebay (knock on wood!)
Tested it with my old el cheapo 80-200mm f/4.5-5.6D lens (all plastic) and borrowed my kids' lego toys for a moment. The setup was great as I have about 14" of distance from the front of the lens to the subject. Using natural window light and a white board as a reflector here is my first try for another macro shot. I changed the in camera's white balance to incandescent to get the blue color effect. Thank you very much for viewing.
Nikon D70, 90mm, ISO 400, f/4.5 at 1/25 second.
