Hey Fred, thanks for your reply. I learning from the responses to my post that no doubt I will be wanting more lens in the future. I have added the wide angle you suggested to my list to consider.
I am very much interested in architecture (exterior and interior) and in landscapes. As of this note, I thinking I should take more than one lens with me just have to decide what it will be... the 18-200, 18-300 or a wide angle. I appreciate your suggestion of the 10-24.
Regarding a camera bag, Unfortunately, I just bought a Lowepro Passport Sling. I searched Amazon for camera bags, the Crumpler never came up. It looks like a great bag, maybe next time.
