The new 300mm/f2.8 AF-S VR II has nano coating (so does the previous VR version) and has updated vibration reduction to provide an additional stop of stabilization. It also has a new A/M mode, which is different from the older M/A mode. In the new A/M mode, to change the auto focus, you will physically have to move the AF ring. See the following link on the Nikon USA web site: http://www.nikonusa.com/Find-Your-N...2186/AF-S-NIKKOR-300mm-f%2F2.8G-ED-VR-II.html Also: http://imaging.nikon.com/products/imaging/lineup/lens/af/telephoto/af-s_300mmf_28g_ed_vr2/index.htm The new TC-20E III is a new design with an aspherical element, different from the older TC-20E II. (The original TC-20E and the TC-20E II are optically identical.) http://imaging.nikon.com/products/imaging/lineup/lens/af/teleconverters/af-s_tc-20e_3/index.htm In conjunction with the new D3S and 70-200mm/f2.8 AF-S VR version 2, it looks like Nikon has a new line up for the up-coming Winter Olympics in Vancouver in February 2010.
