Shot of the edge print on a US $5 bill using OM 80mm F4 macro lens.
No mention of the camera body used, it's a noisy "Toy camera"
according to the experts on this forum :-)

That's OK as long as there's good light.
Here's my same setup on a $5 bill:

-that's a full pixel crop... like I said, not very sharp pixel for
pixel but still amazing detail at 5:1 magnification.

My shot was full frame image, sorry for not pixel peeping with ya.

That's a lot bigger in the frame. A year or so ago we had a
5-dollar-bill-shooting-competition showing this same detail. I think
Brett (Annika) won. What I learned this time is diffraction becomes a
problem at those crazy magnifications. The crop I showed was wide open
at f/3.5 and if I stop down to f/8 you see little circles instead of
detail but f/3.5 has such a shallow depth of field that it's really hard
to even get a piece of paper flat & aligned correctly :-)

More like 4 or 5 years ago, here's the thread:
