Hello all, I am looking to expand my glass in the Nikon family. I just got a D90 and wish to get some nice glass but first here is what I have thus far: On my D50 which would really stay there unless really needed, 18-55mm kit lens, 50mm 1.8, 18-200mm. I also have a good tripod and head so that part is taken care of ahead of time. I would like to consider the 16-85mm for walk around, 80-200mm or the 80-400mm for the distance. On the wide end but not Nikkor the 10-16mm from Tokina. I have been told by a few members that the 80-200 f2.8 is a great lens and I would also then get the 1.7x or the new TC-2.0e III Teleconverter to extend the range. I have gone through my photos and most of my range is between the 16-85 (18-35 really) for most and then 180-200 (only because my range only goes that far) for the rest. Being in the Buffalo, NY area it is easy to go to any park system for wildlife and on the other side of things, architecture is abundant. The question relates to the quality of the said lenses listed and does anyone here really like the ones listed, such as do you have them and are you happy with them? Of course I would buy one now and one around April due to cost of better glass. I also have read some folks don't mind used glass at a great price which leads to this, how can you tell if the lens is in very good condition being used other than by taking what BH Photo have listed per say? Thanks for the input as it's much appreciated.
