The Nikon N90s is a 35mm autofocus film SLR using Nikon’s F lens mount. The name N90s was used for marketing in the United States; everywhere else the camera was called the F90x. This camera was also used as the base for the Kodak DCS 400 series of digital SLRs. The N90s/F90x was introduced in 1994 and discontinued in 2001.
Lens: AF Nikkor 50mm 1:1.8. Viewfinder: Bright viewfinder with 92% coverage, .78x magnification. Four exposure modes: program, shutter-priority, aperture-priority and manual. Shutter speeds of 1/8000 – 30 seconds + Bulb. Flash sync speed of 1/250. Self-timer: 2-30 seconds. ISO/ASA Range 6-6400. DX-enabled (automatically reads speed information from film canisters). The N90s/F90x is compatible with nearly all Nikkor F-mount lenses as well as all Nikon SB series speed lights. Some notable features are missing in the N90s/F90x compared to similar prosumer and professional cameras. These include mirror lock-up, built-in flash and viewfinder diopter adjustment (screw-in diopters are available).
