To do this successfully, you really need a lens with an aperture ring, and even then you are in manual stop down mode. I have shot a few macro shots with a DA lens (specifically the DA15) on a reversing ring, just to see what would happen, but holding the aperture open or part open while you take the shot, juggle the light, etc., is a pain in the backside. The alternative is to shoot everything at f/22 with an incredibly dark viewfinder and not being completely sure of your focus unless you have a hell of a lot of light on the subject.
FWIW this is what you get when you put the DA15 on a reversing ring...
The subject is a friction nut on a spanning wrench, about 10mm across, and the imperfection on the rim is barely visible with the naked eye. It can be done, and the results can be extremely impressive, but the limitations have to be admitted.
