I am looking to up grade in the future my two walk around lenses.
I have the 17-85 IS and the 28-135 IS that came with my 40D.
There are three possibilities.
1. 17-40 L f/2.8
Love the 2.8 , no IS
2. 17-55 IS f/2.8
Love 2.8, IS. Short on the long range.
3. 24-105 IS f/4
IS, Long on tele end, not 2.8, not as wide as the others.
If only Canon could blend these features in one lens.
Product Development.
