Nikon EM
The Nikon EM is a beginner’s level, interchangeable lens, 35 mm film, single lens reflex (SLR) camera. It was manufactured by Nippon Kogaku K. K. (today Nikon Corporation) in Japan from 1979 to 1982 (available new from dealer stock until circa 1984). The camera was originally designed and marketed to the growing market of new women photographers then entering the SLR buyer's market.〔(Nikon | Corporate Information | About Nikon | History | Nikon Family Cousins | Part 11 : "Nikon EM" )〕 The EM uses a Seiko MFC-E focal plane shutter with a speed range of 1 to 1/1000 second plus Bulb and flash X-sync of 1/90 second. It is high, wide, deep and weighed . Unlike most Nikons of the time, it was available only in black. The EM has no full manual exposure mode capability, but instead was intended to be used by inexperienced photographers who could not easily master the intricacies of shutter speeds and f-stops. There were also significant changes over previous cameras in the internal mechanics and electronics of the EM, designed to lower costs. Gone were the tight tolerances, ball bearing film advance, and high-quality titanium shutter. The introductory US list price for the body plus normal lens was only $231 – note that SLRs usually sold for 30 to 40 percent below list price.
The EM accepts nearly all lenses with the Nikon F bayonet mount (introduced in 1959) supporting the Automatic Indexing (AI) feature (introduced in 1977). The contemporary Nikon made AI lenses were the Nikkor AI-S, Nikkor AI and Nikon Series E types. The AF-S Nikkor, AF-I Nikkor, AF Nikkor D and AF Nikkor autofocus lenses are also AI types. Nikon’s most recent 35 mm film SLR lenses, the AF Nikkor G type (introduced in 2000) lacking an aperture control ring; and the AF Nikkor DX type (2003) with image circles sized for Nikon's digital SLRs will mount but will not function properly. IX Nikkor lenses (1996), for Nikon's Advanced Photo System (APS) film SLRs, must not be mounted, as their rear elements will intrude far enough into the mirror box to cause damage.
== Design History ==
Beginning in 1977 with the advanced amateur Nikon FM, there was a complete overhaul of the entire Nikon SLR line. The 1970s and 1980s were an era of intense competition between the major SLR brands: Nikon, Canon, Minolta, Pentax and Olympus. Between circa 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. In addition, because of rapid advances in electronics, the brands continually leap frogged each other with models having new or more automatic features. The industry was trying to expand out from the saturated high-end professional market and appeal to the large mass of low-end amateur photographers who were itching to move up from compact automatic leaf-shutter rangefinder (RF) cameras to an SLR, but were intimidated by the need to learn the details of operating a traditional SLR.
Although Nippon Kogaku enjoyed a sterling reputation among professional photographers with their Nikon F2 of 1971, the F2 was a slow seller to most amateurs and beginners, being fairly bulky, expensive, and complicated.〔Stafford, Simon, et al., ''The New Nikon Compendium'' New York:Lark Books (2003)〕 Although the Nikon midlevel Nikkormat FT (1965) and EL (1972) camera series were made almost as well as the Nikon F and F2, their relatively high price turned amateurs away from the brand, who instead flocked to cheaper models from other manufacturers.
