I was reading about several of our members getting some tubes to do macro work with. I bought a set of three tubes and the adapter off of e-bay just to play with. This picture was taken with me holding my camera in one hand and holding my ring on the thumb of my other hand. Neither hand was braced or being steadied by anything. This is with my Nikon 50mm and a 1x tube. By the way I bid .01 for these and got the whole set to play with. Not bad for a penny. When I get time I will try them using a tripod and stationary subject. This picture is not cropped, Jeff
