I was very interested in your question. If you do get these inexpensive lenses, I would be very much like to see what results you able to achieve with them. Could you post some in due course please?

..don't buy single lenses, just use them if you have them already!

you're right the DOF is nearly absent... especially from 7x t0 12x.
50mm reversed is = +20 magnification.

I use that Canon lens on theFZ20 via a male-to-male ring (inversion rings are only useful to mount reversed lenses on dSLR). The male to male ring is52 to 62: 52 fits with the diameter of the inversed WA and 62 fits on the FZ20 stock plastic adaptor via a 62-72 step down ring.

I guess 70 and 100mm lenses are more easy to use, especially if F2 or larger apertures (less vignetting).
On the other hand 35 and 24mm WA are impossible to use "on the field", only blocked as a microscope.

Tchuanye uses a 50mm on a 4x zoom Canon A610, and this seems to provide more DOF and to be less easy to use then on ultra zooms-

Finally about dipoters I recommend to buy Nikon or Canon, not cheap ones.
