Currently shooting with 40D.
Another vote for the 24-105mm f4 IS USM.
Next up is the 50mm f1.4 USM, and then the wide angle 10-20 Sigma (would love to switch to the Canon).
I would eventually like to change to the 24-70mm 2.8 and then supplement with the 70-200mm 2.8 IS and of course if $ was no object add either the 300mm or the 400mm 2.8 IS USM.
I think I would be satisfied if this mix........
