Macro-madness

This weekend I finally received my long awaited macro-rings.
Just like TMG yesterday showed, they give also a very shallow DoF.
I even had to select a smaller aperture (about F/4) to get more than a fraction of a mm sharp away from the camera.
These bolts are really tiny. The black ones are M2, from a Logitech keyboard.

The green light comes from a green-ish piece of paper I placed on the plate for the flash-reflections.
