How about using the lens reversal technique
with a point 'n shoot digital?
In addition to just using a reversal ring to mount a lens on your DSLR backwards, there is another inexpensive technique that I'm interested in trying. It involves using a "macro coupler". If you could weld two filters (face to face) and then remove the glass, you'd have the idea. This allows you to keep your lens (and all of its connection mounted
normally on your camera, but then screw the
reversed lens on the front of it (like a filter). For example, if the prime lens has a focal length of Xmm and the reversely mounted lens has a focal length of Ymm, then the combined lens will have a magnification of X/Y. One advantage of this technique is that you can still use the camera's TTL metering.

Also, getting more light on your macro subjects is one of the keys if you want to stop down and increase depth of field. You can do that "on a shoestring" using your existing on-camera flash if you build a diffuser out of a milk carton (or other translucent white plastic) that fits on the end of your lens. Your on camera flash hits it and it directs soft light down in front of the lens. Description
here (but I can't get the images to load). Multiple ways to do this. Could be held on by "pinning" it to the front of the lens with a step-up ring (if using a normal macro lens) or with a bayonet mount off of an old teleconverter (or something) if using the reversed lens.
There are so
many ways
to do
this that
it is
limited only
by your
imagination.
