I have for sale a very fine pair of vintage Nikon 7x50 porro-prism binoculars complete with case, Nikon strap, and all four lens caps. These have a 7.2* afov. There is no center tripod screw on this model but since they are 7x50's, that is not really necessary.
These are not the plastic consumer-grade junk that Nikon is unfortunately marketing today. This pair is from the 70's or 80's and is the model that is one step down from the Nikon Gold Sentinel binoculars which were, IMHO, the finest center focus porro-prism binoculars ever made. The difference? This pair does not have as fancy of a covering on the prism and lens housings and the case is not as nice. Optically, they are identical to the GS's and have the famous Nikon Integrated Coating on all air-to-glass surfaces.
Right eyepiece has a diopter adjustment. Collimation is perfect. Lens surfaces are perfect. Rubber fold down eyecups on the eye lenses. There are four minor paint nicks on the edges of the prism housings but no major cosmetic flaws.
These are great optics for panning the night sky. I have several pair and these need a good home where they will be used.
