Thank you everyone for your comments.


Part of me wants to upgrade the lense because of the amazing places my work travels get me to. One week I can be in Kakadu National Park in Australia; the next week I can be in the bright lights of Hong Kong.


I might look at the 17-55. The faster aperture will give me a bit more flexibility. My thinking is that I have all these wonderful opportunities - places many hope to get to - and I would rather know that the shot isn't perfect because of the user, not the equipment.
