Nikon FG - WikiHQ

The Nikon FG is an interchangeable lens, 35 mm film, single-lens reflex (SLR) camera. It was manufactured by Nippon Kogaku K. K. (Nikon Corporation since 1988) in Japan from 1982 to 1986.

The FG was the successor to the Nikon EM camera of 1979 and the predecessor of the Nikon FG-20 of 1984. These three cameras composed Nikon's first family of ultra compact 35mm SLR camera bodies. Although the FG had a much less advanced shutter than the more expensive Nikons of the day, it had a very sophisticated electronic design compared to earlier electromechanical Nikons.

Features

First Nikon SLR with programmed auto-exposure (AE).
First Nikon SLR with TTL (through the lens) flash exposure control from a standard ISO-type hot shoe.
Electronically controlled focal plane shutter.
Exposure compensation dial (−2 EV to +2 EV).
Audio warning system – advises of under or over exposure.
Back-up mechanical M90 and bulb shutter settings enable the use of the camera when batteries are drained.

Body and Design

Body Construction

Copper silumin aluminum alloy body
Polycarbonate exterior
Leatherette (synthetic) covering and was also used previously in the Nikon F3 introduced in 1980. TTL OTF flash exposure control is more precise than previous methods as it measures the flash exposure at the film plane rather than at the flash itself. Correct flash exposure is achieved via a SPD cell at the base of the mirror box, which measures light reflected back from the film plane.

The FG can only connect to flashes via the hot shoe connection, as it lacks a PC sync socket. Flashes which do not have a hot shoe can be used with a hot shoe-sync cord adapter.

Lens Compatibility

The FG requires Automatic Indexing (AI) Nikkor lenses for P and A modes to function. Lenses with AI capability include AI and AI-s type Nikkor lenses and Nikon Series E Lenses.
The following Non-AI and AI-converted lenses are not usable with the Nikon FG:
Non-AI (requires AI modification)
AI-converted 55mm/1.2 ser.# 184711–400000
AI-converted 28mm/3.5 ser.# 625611–999999
AI-converted 35mm/1.4 ser.# 385001–400000
Fisheye 6mm/5.6 (requires mirror lock-up)
Fisheye 10mm/5.6 OP (requires mirror lock-up)
PC Nikkor 28mm/4 below ser.# 180900
PC Nikkor 35mm/2.8 ser.# 851001–906200
Reflex Nikkor 1000mm/11 ser. # below 1430000
Reflex Nikkor 2000mm/11 ser. # below 200311
Zoom Nikkor 200-600mm/9.5 ser. # below 301922
Zoom Nikkor ED 180-600mm/8 ser. # below 174180
Zoom Nikkor ED 360-1200mm/11 ser. # below 17412
Focusing unit AU-1
G-type lenses lack an aperture ring and do not couple with the indexing ring on the FG. The P mode does not function. The A mode will suggest a shutter speed for the available light. The aperture can be stopped down by slightly unscrewing the lens.

Nikon Speedlights

The FG can be used with any dedicated Nikon speedlights (flashes) which support TTL flash exposure, and any non-dedicated flash units in either automatic or manual modes.

Dedicated, hot shoe mounted Nikon speedlights available during the time the FG was manufactured were the SB-E, SB-15, SB-16B, SB-18 and SB-19.

Background and design history

The 1970s and 1980s were an era of intense competition between the major SLR brands: Nikon, Canon, Minolta, Pentax and Olympus. This was in part a result of rapid advances in electronics at the time, which allowed new cameras to be released more frequently and with more automated features than had been possible previously.

Between c. 1975 to 1985, there was a dramatic shift away from heavy all-metal manual mechanical camera bodies to much more compact bodies with integrated circuit (IC) electronic automation. As a result of the manufacturing climate of the time, the EM and subsequent FG and FG-20 were released with much lower price points, and more compact and user-friendly bodies than previous Nikons, to appeal to the amateur photographer market.

The FG was intended to improve on the short-comings of the EM (which had no manual override) and to compete with other programmed SLRs of the time, such as the Canon AE-1 Program (released 1981) the Minolta X-700 (released 1981) or the Pentax Super Program (in the USA/Canada; Super A, rest of the world; 1983).

Market Reception

The FG was well received by many amateur photographers, but was criticised by others due to the lower build-quality and reliability when compared to other Nikons of the same era. The FG has known reliability issues, particularly with its shutter components and ICs.

Compared to Nikon EM and FG-20

The major improvements of the FG compared to the EM were improved exterior cosmetics, internal printed circuit electronics, the addition of the manual exposure and programmed autoexposure modes, and provision for TTL flash automation.

The FG-20 is a simplified version of the Nikon FG, with no Programmed AE mode, no TTL OTF flash, and no exposure control, but retaining Aperture Priority AE, and manual and auto flash exposure control.
