I have the 60mm f/2.8 AF which I've used for some flower and still life photography in daylight. I'd like to try photographing insects too, but haven't got around to that yet. With the 60mm, you have to get really close to get the 1:1 magnification; the 200mm will give you more room to work with. I've heard good things about the 55mm but I don't have it. Results with the 60mm have been pretty good for me.

Photographing everyday things really close-up also sounds very interesting....
