Some time ago, I bought a very, very bargain basement loupe. I bought it down at the swap meet maybe 15 years ago. Don't know why I bought it, but I don't think I paid more than about a buck for it:
A friend of mine took some photos of a knife using a loupe, and they weren't bad, considering. I thought I'd try it, just for fun. I held the loupe up in front of the lens on my point & shoot, in this case a Canon G12. I was hand-holding the loupe as well as the camera, so I knew these weren't going to be real sharp. Add to that what is probably a pretty lousy optic in the loupe, and there's a lot of room for improvement. I'm going to try it again with the camera on a small tripod, triggered with a remote, with the loupe somehow affixed to the lens.
Anyway, this is what I ended up with:

A portion of the back of a half dollar:
Anyone ever try this?
