The Nikon FSB-8 bracket was announced in Japan on February 9, 2011 and today it’s official in Europe. The FSB-8 is still not listed on Nikon USA website.
The bracket will allow you to attach the Coolpix P300 camera (the model with the f/1.8 aperture and no RAW capabilities) to Nikon fieldscopes, spotting scopes and EZ Micro products (see the related Nikon Fabre Photo EX review).
