Best Macro Lens for..........?

a) plants
b) close up textures of certain materials like wood, trees, brick etc..
c) insects

im a complete nooby, so please dont be harsh to me,

I adore the 60mm macro but you might find that for buggies the 100 will serve you better as you have a bit of working distance and won't crowd them as much. There are also longer macro lenses out there that produce really nice images.

Any of the macro lenses around 100mm will be good- Tamron 90,canon 100 and sigma 105 - all are equally sharp around F8- F13.
