Three weeks ago my husband bought me a wonderful present - a Canon EOS 20D. With it (Kit) came a EF-S 18-55mm f/3.5-5.6 lens, and a EF 55.200mm f4.5-5.6 II USM is on order. I really like Macro photography, though. So, I am looking at the EF-S 60mm f2.8 Macro USM, and the EF 100mm f2.8 Macro USM. Has anyone used them with an EOS 20D before? If so, how do you rate them? Which one would you recommend? I only ever used a basic film SLR before, so this is quite new to me, so any advise would be greatly appreciated.
