Would I be nuts for wanting to trade my 24-70 L for a 24-105 f4 IS L? The thing is I don't shoot too much indoor natural light and would mainly use this for outdoor photography. Not sure about the IS if it makes any real difference.
I would also consider a 17-55 IS f2.8 lens but EFs is sort of a scary thing, even though I could always resell it if I bought a 1.3 or higher camera.
Has anyone here ever considered this and made the switch? Or tried them side by side or tried out a buddies and compared?


And I wouldn't trade the 17-55 for anything. It's that good.
