Nikonos III is an all-weather camera featuring its highly water-tight, pressure resistant and corrosion resistant properties. The Nikonos III also employs durable mechanisms not achieved by any other camera. Equipped with an illuminating window-type bright frame viewfinder with a brighter field of view and a crisper, clearer frame. Its film holding spool contains two grooves for easier film loading, the hinged pressure plate opens in a downward direction and has equal frame-to-frame spacings on a roll of film.
