Raynox DCR 250 super macro lens, attached to Panasonic 20mm f/1.7 lens via 46mm to 43mm stepdown ring on Olympus PEN E-PL1 camera. Didn't realize that I had a big blob of dirt on the Rayno and had to crop off a lot of the bottom of the image. I suspect it may have been pollen since you have to work very close with this lens.
