Thanks for the reply. I'm going to stay with my current lenses for now, and perhaps in the future, pick up a non-prime 10-24.
I own a circular polarizer (Tiffen), and plan to use it on a lot of my outdoor landscape shots this summer. It's been so long since I've used it, what are the rules of thumb as to when to, and when not to, use it? Is my Tiffen good enough to use with the Nikkor 18-55 and 55-200, or should I be looking at another brand?
