I have heard good and bad on the 14 which makes me think there might be sample variations or it could be personal, I have some quality lens that I own, tested and they're good yet I still don't like them and never use them.. I have had issues with sample variation before but always third party. All my Nikon stuff has pretty much been spot on, some I just don't like. 70-210, sharp, fast auto focus and reasonable light. Hate it yet it doesn't do anything really bad. 80-200 2.8 does everything great and I have total confidence in it except it weighs a ton, stays on my shelf at home unless shooting sports. the new Nikon 70-300AF-P would have been great except I don't have a body that will support it fully. Anyway, I have a 16-50 coming to get started with, also an adapter. If I get a good copy it will be fine to learn my way around. I have seen some really good stuff out of this lens and while the 18-55 appears to be very good I will trade for the extra 2 mm in wide. I would love for the 14 to be THE LENS and will try one from KEH so I can send it back if we don't hit it off. Then it will be on to the 16 or the 10-24 for my wide stuff. A 56 and then a 55-200 will come along at some time. That should do it but I know better. There will always be another lens.
