To show what is possible, I used a reversal ring, extension tubes and bellows at full extension. Lenses used were M 50/1.7, M 28/2.8 and M 20/4. You can probably guess which is which. The first image was made with daylight. For the other two I added a couple of LED lanterns, hence the difference in color. The rig was casting its own shadow on the subject. No post-processing except for raw to JPEG conversion was done. For EXIF peepers, the date in the camera was wrong.
Edit: those are the markings on a plastic metric ruler. I didn't feel like looking for Lego bricks.
