Home Forums Gear Photography Camera and Lens Question

I have a Nikon D50 that I have had a lot of fun with. I have been thinking of getting a Nikon D90 and a new lens.

What advantage will the D90 give me over the D50?

Second, what lens would you suggest. I like to shoot wildlife and scenery. I have a good Wide Angle....I would love to have a 28-500 but I dont' guess that is possible.

I have a Quantery 70-300 lens that I bought back when I had a Nikon N60, my problem with the Quantery is that a lot of my shots are out of focus. I don't notice on the camera LCD but when I get back to my computer it is a useless picture.

Any help or suggestions will be appreciated.
