This is my nineteenth Nikon camera. I received it the day before yesterday (25th April, 2013) Its a Nikon FA. Its shutter does not work and need repair, but I will keep it as my camera collection. 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. The Nikon FA was the world's first camera with Matrix metering. It has a little button just below the self timer on the lens mount switch. Push it in for old-fashioned center weighting or leave it out for Matrix metering.
