If you look at some of the D7000 press release pictures on Nikon USA website, the EXIF data shows a lens that I cannot identify in the current Nikkor line-up:
picture taken with D3x (full frame)
focal length: 150mm
max aperture: 3.3

The low-resolution versions do not have any EXIF data.
What do you guys think? Sigma has a similar macro lens @ 150mm f/2.8. This could be a new Nikon lens or of course the EXIF data could be manipulated (but why?).
