Of particular interest are the first two photos in that post, which were shot with the Nikkor 55-200mm VR lens — you can see also see the Nikkor 55-200mm VR sample (and another at 160mm) at 200mm focal length, full-size — pretty impressive.
He’s provided samples at full-size for the images taken with other lenses too, in order to compare the sharpness of the “consumer” 55-200mm VR zoom lenses against the professional lenses from Nikon. The full list of lenses are:
• Nikon 55-200mm f/4-5.6G ED IF AF-S DX VR Zoom Nikkor Lens (UK)
• Nikon 17-55mm f/2.8G ED-IF AF-S DX Nikkor Zoom Lens (UK)
• Nikon 70-200mm f/2.8G ED-IF AF-S VR Zoom Nikkor Lens (UK)
• Nikon 105mm f/2.8G ED-IF AF-S VR Micro-Nikkor Lens (UK)
