I currently use a D60, and have a Nikkor 18-55. 55-200, 300 F4, and TC 1.4, all AF-S. Ever since buying the 300 a few months ago, I've done nothing but birds and wildlife, I've been so happy with the glass on the 300.
Next month, my daughter and I are touring middle-America from Carolina to Kansas, with a few points further south. I'm hoping to do some good general landscape photography: hills, lakes, thunder-heads, farm buildings, etc.
My guess is that I will not be as happy shooting the above with my current zoom lenses, as I have been shooting birds with my prime.
Question #1: Is the quality of the glass on the 18-55 about the same as on the 55-200?
Question #2: Do you agree that I am unlikely to get professional-looking photos from my 18-55 and 55-200?
Question #3: If you were going to buy ONE prime AF-S Nikon lens for general landscape use (and you already had a TC 1.4), which would it be?
