Anyone as crazy
I've read from many people this this is a very good lens for the money considering everything it does. I've seen great pictures to back up those claims. For me, though, it wasn't worth the money. I can buy a whole host of lenses that I like better for that kind of cash.
When I bought my D90, I got the 18-105. As a kit lens it was inexpensive I the range is perfect for to use as a casual/walk-around lens. Beyond that, I want fast, very sharp lenses and a constant aperture. For me, this means primes and expensive zooms.
