I started with a 1D3 and a 24-105 back in '07. Four months later, added a 70-200/2.8IS, and eight months after that added a 16-35/2.8II. Eight months after that, I rented the 24-70/2.8 and had to have it. Once I finally got it, the 24-105 moved to my wife's bag, which moved her 28-135 to the shelf, and I've never looked back. f/2.8 gives me so much artistic power, and stop-action benefits too. Plus, I feel like the 24-105 is a great lens but without any magic...even the old-model 24-70/2.8 has a certain sparkle to it.

Now that I've "gone Black Rapid" (none of our cameras have traditional straps now), I have occasionally grabbed the 24-105 for true one-lens no-bag adventures. Nonetheless, a 24-70/2.8II is on my wishlist, which will move the old model 24-70/2.8 to spare/remote duty.
