The Nikon FA was most advanced manual-focus camera ever designed by the company. According to Ken Rockwell “the only camera on earth that can give Program auto exposure along with Matrix metering with all AI and AI-s manual-focus lenses”. The camera was advanced enough for Nikon to produce a gold plated exotic leather edition. Nikon billed the professional FA as the “Technocamera” at its 1983 introduction. A decade or two later it’s still Nikon’s most technically advanced manual focus camera. It was discontinued in about 1988.
This is the Demo version signified by a red letter ‘D’ preceding the serial number at the rear of the camera to the right hand side of the finder eyepiece. It is otherwise a fully working camera.
