I'm nowhere near my best effort last time, so I'm not finished yet
Johan, nice site

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 !!

Is that bacteria growing on there?

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

Thank you Darkmunk!

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!
