I'm formulating a plan for the future. First, I love the 18-200 on my D90. I know it's not perfect but it does a lot of things great. I like taking my camera hiking and climbing and taking one relatively light lens is a huge plus. I've begun to want something a little more out of the lens though. It's soft at 200mm and sometimes 200 isn't enough. (though I can live with it fine). 18mm seems more than wide enough for most applications. I think it takes brilliant pictures in the 50 - 75mm range and around f/5.6. I've been thinking about the 70-200 a lot and I know it's at the top of it's class. If I sacrificed and carried two lenses what would the group recommend to fill in on the wider side. The 17-35? I have a 50mm but i don't really want to carry 3 lenses. The 18-200 is not that heavy, perhaps I would just carry it to cover the 18-70 range. I would probably do that until I could save for another lens anyway. Any non Nikon recommendations? Right now I'm really locked in on the 70-200 but undecided on the wider end. Thanks for any advice. I really wish 18-200 was "pro" quality. The range probably makes that pretty difficult.
