Awhile back I ordered a reversing ring to try some macro with. Sadly, I'm not smart enough to order the right size, and postage to return it would be more than I paid for it. Anyway, this PM I found a dead red wasp in my clothes washer (warsher, if you're from the South). So I set up a flashlight, put on the reversing ring, and held my 18-55 lens against the ring. After a few failed attempts, I got this one. Nothing to brag about really, but it's a personal best for me. Not hard to get a personal best when you've only done it once. BTW, one reversing ring for Canon EOS mount threaded for 55mm lens is free to a good home.
