Does anyone know a lens that turns either the 16x or 3x lens into a macro?
Thanks,
Bryan

Bryan,
I've never used these, but Century Optics (http://www.centuryoptics.com/products/prodv/xl1/achromatic_diopters/index.htm) seems to have something that might fill your bill.

What are you trying to shoot and how large do you want to make the subject? The least expensive way to go is with the screw on close-up adapters (diopters) that Ken suggests. They come in different magnification strengths or powers. The better quality adapters use multiple elements (usually 2) and this allows for better optical performance (better flat field performance, less distortion). Both Canon and Century make 2 element adapters, there are probably others as well. A 72mm Century diopter is around $250

If you need extreme close-ups (higher magnification) use the EF XL adapter and one of Canons EOS EF lenses. The very best optical performance will be obtained from one of Canon EF macro lenses. The 50mm lens on a 1/3 inch chip camera become the equivalent of a 350mm lens on a 35mm camera. This may be an advantage by giving you a greater lens to subject distance. Nice for working with poisonous snakes for example. The cost of the adapter and 50mm EOS EF lens should be around $700.

I'm getting some great results with a HOYA diopter set. Cost about $60-$70 for all 3 (+1, +2 & +4). Of course now I'm stepping up (or should say back) to an EF + lens so I can back up a little from the subject. If you don't have to worry about being close, the (cheap) diopters are at least a great start.

Don't forget the manual 16x has macro capability also. It's a seperate, small ring near the camera end of the lens that needs unlocking and which twists to give you adjustable macro. It works really well and this was one of the reasons why I got the lens in the first place...
