K-5, with a Rodenstock Heligon 100mm f/1.6 at full opening.
It's an X-ray lens, adapted to K-mount with gaffa tape and an extension
tube (kinda), making it a fixed-focus macro lens.
C&C appreciated. This is very much an experiment.
I think that you are opening new frontiers in lomography. I wouldn't
recommend it as an "every day" sort of effect, but it is very interesting.
Certainly not your everyday effect. :-)
Old x-ray lenses is no frontier anymore, if it ever was. Take a look at
this group at flickr, for example:

I wonder if you could use one of those lens mount adapters that has a
corrective element to allow infinity focus so that you could at least
focus out a few feet and use it as a soft focus portrait lens.
Actually, the lens is mounted in an old A-50/1.7 with the glass removed
but aperture mechanism intact. Got it for free because the thread in the
focusing helicoid was broken. I guess it would be possible to mount it
in a shorter tube to achieve longer focusing distance, but I really like
the exposure automation I get with the A- lens.
Or, if you were really silly, you could try your focus stacking with
this lens and see what sort of crazy images you get. :-)
:-)
I guess the stacking software would try its best to remove the faults
that makes it special. I've used it at f/16 too, and it's razor sharp
and behaves mostly like a normal lens. No fun in that. :-)
