polecam lekturę na temat 100/2.0:

i cytat, żeby za bardzo nie szukać:

If you need a 100mm lens and can get by with a minimum aperture of f/2.8, I recommend you get the slightly more expensive Canon EF 100mm f/2.8 USM Macro Lens. You get a very sharp lens with an additional capability - 1:1 macro photography. I do prefer the handling of the Canon EF 100mm f/2.0 USM Lens over the 100 macro.

If you need a fast-focusing low-light action sports type of lens, the Canon EF 85 f1.8 Lens or the Canon EF 135mm f/2.0 L USM Lens would be better choices (in my opinion of course).
