I just received my new Canon 24-105 L glass lens, and from first pics I'm happy I sold my 28-135 & bought this. In fact it's the last lens I need to complete my kit. No, really! (Well, I might want a tilt-shift one day, but...Just kidding, honey.)
One thing I noticed is that the zoom mechanism is noticeably stiffer than my 17-40, 70-200 or the old 28-135. Is this normal for this lens? When I first mounted the lens I was afraid there was a problem with it.
