24-70 L - A Step Up from the EF 17-85?

[alexniedra]

I'd skip the 24-70L

Oops! Already got it. [] I really like it so far.

Try the new 15-85mm zoom, or better yet, the 17-55mm EF-S.

I was considering the EF-S 17-55, but I want to maintain full-frame compatibility. I may upgrade to full-frame as my shooting experience (and needs) grow.

Its the lens others are compared to for that focal range on a EF-s camera, and its wonderful.

I agree with you. The EF-S 17-55 is simply superb optically.

its not great on a crop camera,

For my shooting style, the focal range (and compatibility) offered by the 24-70 L is perfect.

and very front heavy on a smaller camera body, the balance is poor.

I agree. Luckily, I'm using the battery grip on my Xti. On the 40D, the balance is much better, but overall, the setup is front-heavy. Maybe a 1D Mark III will solve this issue. []
