The Nikon FG was introduced 4 years after the super compact Nikon EM in 1979. There were many innovation and sophisticated improvements incorporated within an identical size camera body. It was Nikon’s first multimode AE camera. Unlike the only black body EM, it came with two choices of either black or chrome. The Nikon EM was a simple automatic exposure SLR camera with only a sole aperture priority AE mode, a mechanical shutter speed of M90 and a bulb mode to spare in case of battery failure. The FG introduced Aperture priority and Programmed Auto mode in addition to manual exposure control. Manufacturing and assembling processes were automated. No less than three IC chips – bipolar, bi-MOS and ISL – were integrated into a hybrid configuration on one board for the micro electronic circuitry. To make sure the FG worked with high accuracy and stability, several assembling processes were automated – Automatic Mounting on the FPC, Automatic Assembly of the mechanical units, and Automatic Adjusting/Testing of electrical circuits. The body featured reliable operation and energy-saving circuitry on the inside, and a durable die-cast body on the outside. Beneath its leatherette covering, the basic structure is still an Aluminum die-cast structure.
