The Nikon FG-20 is a 35 mm film single-lens reflex (SLR) camera with interchangeable lenses. It was released in 1984 by Nippon Kogaku K. K. (now the Nikon Corporation ) as the successor to the earlier EM and FG cameras. It is actually a downgrade from its most direct predecessor, the FG, lacking the FG's program auto exposure mode. It uses the same vertical-travel metal focal-plane shutter as the FG, with electronically timed speeds from 1 to 1/1000 second as well as bulb and a mechanically timed 1/90-second speed.
20-571: The FG-20 could be considered a variant of the FG, as the differences between the two are the omission of program mode, exposure compensation dial, and TTL/OTF flash metering from the FG.

The camera body was redesigned with curved surfaces, the shutter release button on the front on the body rather than the top and the film advance on the back of the camera. New features included a 48mm f / 2.0 Nikkor lens, a new instant return mirror design, improved pentaprism viewfinder and
100-407: A glass pentaprism; no instant-return mirror mechanism or mirror lock-up option; no provision for motor drives; and lesser build quality. Built-in metering — a first for a Nikon camera — used a selenium cell above the lens. Controls for meter-coupled aperture , shutter speed and film speed settings are on rings around the lens. Optional attachments via the filter ring were available to convert
120-514: A hinged back for more convenient film loading. In 1965, the first of the Nikkormat series was introduced, a Nikon-built amateur market camera using a Copal Square shutter. The Nikkorex F was discontinued in 1966, and Mamiya sold the design to Ricoh , which produced the related Ricoh Singlex and Sears SL11. The Nikkorex Zoom 35 was a variation on the Nikkorex 35 II.

Notable Nikkor branded optics have included: Nikon introduced the Z-mount in 2018 for their system of digital full-frame and APS-C (DX) mirrorless cameras . All of Nikon's Z-mount lenses are Nikkors.

Instead of a 50mm lens, the Nikkorex Zoom 35 has a fixed 43-86mm f / 3.5 lens that is a predecessor to the Nikkor F-mount 43-86mm lens released later in 1963. Like the earlier fix-lens Nikkorex models, virtually all control of the camera was done using rings on the lens. Shutter speed, aperture, film ASA (ISO) number, zoom and focus each had

Prior to approximately 1976, most Nikon lenses had a suffix appended directly after the "Nikkor" name that was used to denote the number of optical elements in the lens design. For example, a lens with eight elements would be marked "Nikkor-O", and a lens with eleven elements "Nikkor-UD".
