I have preordered the new nikon D300 body only, and I am trying to figure out what would be some good lenses to buy for it. I would like to shoot portraits as well as landsacape and wildlife photos. I have heard about the new nikon 24-70mm/f.2.8 and wonder how it wouild compare to the nikon 17-55/f.2.8 for portraits and all around use. What do you think?? I have also heard that it may be several months before the new nikon lenses are released, even though they claim they will be released in November,2007. Any help/and or reccommendations regarding camera lenses for the uses I have mentioned would be greatly appreaciated.
