I'm working on a pretty comprehensive post on inexpensive alternatives to a real, 1:1 macro lens. Been rainy here lately and haven't been able to shoot many examples.
For the pic that follows, I screwed two lenses together, face to face, attached one to the camera, and had the barebottom end of the other facing the subject. Only got one good shot before I gave up on that technique - was windy and the light was bad, too. But...I did like this pic.
