There is a third option - it is called a Teleconverter. ...)

closeup ring set.

How closeup do you want to go?

Jim makes some excellent points. I think you have to work your way from the
bottom up:
1. How close do you want to get?
2. What do you plan on carring with you normally?
3. Is this for spur of the moment macros or a dedicated trip to the
botanical gardens?
There are many more options than close-up rings and diopters. Reverse
lenses, dedicated macro lenses, bellows, and the teleconverters, close-up
rings (extension tubes), and diopters previously mentioned. You can even
combine some of them. For a good discussion and explanation, I suggest John
Shaws' "CloseUps in Nature." It will explain the possibilities of each, and
also discuss techniques, exposure and lighting, and other equipment
(rails). Without knowing your intentions (above questions), it's difficult
to offer a one solution fits all suggestion. I will say this:
1. Extension tubes keep the quality of your original lens. No extra glass
to add their own imperfections.
2. Diopters are easier to carry and quick for an occasional macro shot and
work great with zooms (70-200 or 100-400) and give good "on the fly"
flexibility. Get a two element one (Canon D series, 250D or 500D). The
single element ones are poor quality. You can see it through the viewfinder
when you put them on your lens.
Cheers, JD
