I just ordered the 70-200 2.8 IS II. This combined with my 17-55 2.8 should satisfy my lens/gear needs for a long time. At least that is what I was telling myself when I hit the "Purchase" button.
Except maybe just a monopod to shoot my 5-year-old doing soccer.
And maybe just a 1.8 nifty 50 for playing with.
And I am just assuming my existing backpack will fit this beast...
