I hope you're kidding. Obviously quality glass is super important, but there's no way I'm spending more on ONE lens than on the entire body.
But you're happy to spend all that money on a D200? If you're planning to invest long-term in SLR systems you may have to accept that spending more on one lens than on the body is really not that unusual. You've decided on one of the best bodies available, so why not take the same approach to glass and make the most of the camera's potential?
