I have started to research an uprade for my D80 which I have been using for sometime. I have the kit 18-135mm lens plus a Nikon 50mm prime lens - a Tokina Macro lens - and a Sigma 120-400mm (bought as I went to Yellowstone this week!). If I upgrade the Body I will go to a D90 - which gets nothing but rave reviews. Having said that I don't think I need live view or video.... So last night I thought about upgrading my lens. I might not do it all in one hit - but if I don't get the D90 body, I would be looking at getting the Nikon 18-200mm VRII as a replacement to the 18-135mm - and at some point I want to add the Nikon 12-24 (or 10-24) or the Tokona 11-17.... Wide angle would have been great in Yellowstone too!! If anyone has observations or comments I would be very glad to listen. I am an amateur and at the moment I think I am leaning towards improving the my lenses .... Thanks to all who help.
