Finally i tried my new Canon 7D with the 17-85 IS USM.
I can't describe how good it feels shooting now, coming from a 400D/rebel XTI.
Once the camera arrived i only had the standard-non-IS 18-55 from the 400d and boy how bad it was.

The IS is so useful, i just can shoot at 1/focal lenght every time without having to do multiple shots or being scared of shaking.
Also all my previous lenses suffered from back focusing,but this finally is the sharpest.
It suffers a little from cromatic aberration and i don't have a hood yet, but who cares...
The focal range is perfect for the
