Nikon has released prototype images of a Nikkor 800mm f5.6 AF-S VR super telephoto lens. This is the longest focal length that has been made available on any system in quite some time, and seems to be aimed at bird watchers and astro photographers.
What blows my mind is the multiplier effects when used with a teleconverter or on a DX camera. This would be 1,600mm with a Nikkor TC20 II or 1,200mm on DX. With a teleconverter on a DX camera this would be a crazy 2,400mm f11 lens!! What about on a Nikon V1? An insane 4,500mm!!
