    Those are called Close Up diaopters. You screw them onto the front of your lens and they allow you to shoot macro shots. The numbers refer to the "power" of the diaopter. Always use a tripod when shooting macro shots for best results.

    What is the advantage to using a true macro lens over a diopters? Less loss of light?

    The only advantage I can think of is that a diaopter is cheaper. Actually, the other advantage is that you can buy different diopters in varying degrees of magnification. The dissavantage is that you're adding more glass to the front of the lens and a cheap diopter won't be as optically clear as a good lens.

    But the real question is, will the added glass cause a noticeable difference in the quality of a picture? (I'll probably end up buying a macro lens anyways, just for the peace of mind and because I am paranoid lol)

    You won't notice any difference in quality unless you stack a bunch of diaopters together or plan on making extreme enlargements.
