I recently got a Canon EF 24-105mm f/4 L IS lens for my XTi. I also have a Canon EF 17-40mm f/4 L lens. The 24-105 has a super tight zoom ring compared to the 17-40. On the 17-40 the zoom ring is super smooth and I can accurately adjust it with just my thumb. On the 24-105 I really need to grab it with two fingers to turn it. It works, but it's not smooth.
Is the tighter zoom normal for the 24-105 (due to its heavier weight perhaps)? Or did I maybe pick up a not-so-good copy?
