Heres the answer to what was on the 2 pictures I've posted yesterday:
portrait of a (beaten-up) butterfly. Done with MP-E lens on 5x
magnification at f/8. I knew that f/8 (actual f stop was 48, see
explanation on http://pikespeakphoto.com/tests/canonlens_mp-e.html)
was too low and one can't get too sharp picture with it (the proper
setting should be f 4). Still, despite the 20 pictures per chip, there
were out-of-focus spots. With f/4 I'd have to make about 100 pictures
per chip and this was prohibitive. It's a large magnification. The
diameter of the eye (narrow side of the oval) is 1mm. Interesting and
unexpected were scales behind the eye (we thought that they covered
only the wings!) and hairs on parts of the eye.
Sorry for a large file size, but I think it's worth it.
Blue is an LED light, and the rest - standard incandescent (lamp) light.

Cheers,
Wojtek
