I used some Kenko extension tubes and my upgraded Canon 50mm f1.4 lens to capture a very close shot of my wife's bracelet/chain. This shot was done with a tripod, remote shutter release, and natural light. Settings were 2 seconds at f/10, iso 100, 50mm. Taking a subject that is fairly mundane and turning it into something abstract is a lot of fun. I strongly recommend giving extension tubes a try. They retail for about $200, but can be found used for much less. I recommend buying a used set because there is not much that can break or cause them to malfunction.
