buying a 7d now need critique on lenses.

[Thor]

Hi, Im buying a 7D and im just wondering about a few of the lenses that i am getting for it.

im stepping up from a fuji s9500 with a fixed lens. (entry level dslr and a few years old)

*Canon EF 70-300mm f4-5.6 IS USM for sports and telezoom.

*Sigma 17-50 2.8 or a 50mm Canon f1.8. for portraits and walking around people shots.

*Canon EF 100mm f/2.8 USM or Sigma MACRO 70mm F2.8 EX DG Lens for macros.


*Tamron SP AF 10-24mm f3.5-4.5 Di II LD Aspherical IF Lens for my landscapes.

These are the lenses i like. But i am up in arms about the macro lenses. what are the extension tubes and ad on macro lenses like for close up quality?

your criticisms are welcome.......
