Someone I know who has a D200, and bought a D300 last week. However, his main lens is a 18-200 Zoom (he has the 12-24mm, and the 200-400mm, which he rarely uses), and his rationale is that with one lens he can do 99%. Why is it that people are willing to go from a D200 to a D300, but won't buy the better Nikon glass within the normal focal length range, eg., 14-24mm, 24- 70mm, 17-35mm, 28-70mm? Note: This person has no money problems. My basic question is, which one is better: (a) D200 with a 17-35mm, and a 28-70mm or (b) D300 with a 18-200mm, or a 18-70mm NOTE: Assuming that only the 17mm to 70mm focal length is used for comparison. Why is it that people are quick to run for the D300, but stay with the cheaper lenses?
