On a Horse Called Autumn

I used a Nikkor 200mm f/4 AI lens, made sometime between 1977 and 1981, in combination with a Nikon TC-16A teleconverter on a Nikon D2Xs camera. This provided a focal length of 320mm and a field of view equivalent to almost 500mm on a full frame SLR.
The TC-16A was designed to work with Nikon's first AF cameras during the 1980s. It enables photographers to mount manual focus lenses and, within certain limits, use them in automatic focus mode. By some strange design quirk, it functions on the D2Xs, Nikon's last professional camera to use the APS-C format.
