Nah, was just musing. Too busy playing with UV fluorescence at the moment.
Thank you Darkmunk!

Ok had another go
K30/teleplus2x macro focusing converter@1x1/set of tubes/Pentax dfa 100mm@1x1 and a reversed m50mmf1.7@f16 lit with an led inspection pen.
12sec delay and remote shutter release.
I think I will stop now because I think I can see bacteria on the penny !!

Magnification: pretty good.
Lighting: hmm.
Sharpness: Where?
Tried flash this time, instead of a great big sunny window. Looks like I need to diffuse it somewhat
It just picks out all the crystals or tiny facets.
I think the the cheap 2x convertor is solely responsible for trashing the sharpness, either through not passing the resolution, or just being a bit crap
100mm extension, 2x convertor, 100mm macro - f5.6, 28mm reversed - f2.8

Here's exactly the same combo as above (both on the K5iis BTW), but this time with lovely diffused daylight from the window, and a 3 second exposure instead of harsh flash with distracting specular highlights.
Good to be reminded - lighting is everything.
Oh... back to the original angle too, which helps the relief and composition.
This is about 20x macro I think. DOF 1/3rd mm

Just wondered if you have seen these standard UV P60 dropin modules http://www.batteryjunction.com/p60-uv-buld.html . Then you can get a decent metal P60 torch body to use it in for another $20 or so. I would hope that would perform a lot better than the 72 LED style jobbies but if it's crap you can always use it as a normal torch

It's not really a competition; it doesn't end, it's just an open-ended contest, so no rush

Thanks Gwing! Not quite what I'm looking for because it's 395nm-400nm which is not quite low enough and a lot of blue, but great to know about!
