With a good MP camera and the right lens, it might be possible to get close without having to get REAL close. Otherwise, I'm not sure how to light a macro subject without a light ring. Might be good reading to find out.
Still have to figure out how to make the extention tubes work with our camera and play with that a bit. maybe this weekend.
