I shoot with a Nikon D80 and have a few lenses.
My first lens was the 18-200 VR (two years old now, I was considering selling but decided against it), it does have it's limitations but as an all around walk around lens, it's fantastic.
My pros: large range is covered, VR for stability, less lenses needed to carry when traveling light, built Nikon strong, never had any issues at 18mm what so ever.
My Cons: Lens creep when looking straight up or down, a tad heavy, not f/2.8, high ISO noise, not the greatest in low light and some vignetting.
I have since added a few lenses to my bag, Nikon 50mm f/1.8, Tamron 90mm f/2.8, Nikon 80-200 f/2.8.
Currently on the hunt for the Tokina 11-16mm (destroys the Nikon 14-24mm) regardless what Ken Rockwell says.
Have a look at my
flickr page for examples.
Send me a PM if you have any specific questions related to the pics or anything else.
Good luck!
