Nikon's advanced autofocus SLR — the F-90, electronic, 1/8000s, matrix metering, Nikon F, 1992.
The Nikon F-90, introduced in 1992, was an advanced enthusiast and semi-professional autofocus 35mm SLR that succeeded the F-801 line with faster autofocus. It was sold as the N90 in the United States. It belonged to Nikon's autofocus range of the early 1990s and used the Nikon F bayonet mount, part of the long-lived Nikon lens system.
This is an electronically controlled 35mm SLR on the Nikon F mount, with a vertical-travel focal-plane shutter that is electronically timed, offering speeds to 1/8000 second plus B, with flash sync around 1/250. Metering includes matrix, centre-weighted and spot patterns; exposure modes include programmed, aperture-priority, shutter-priority and manual. It provides faster phase-detection autofocus than its predecessor and integral film advance. As an electronic body it depends on batteries to operate.
The F-90 suits enthusiasts and semi-professionals wanting quick autofocus, a wide shutter range and full metering in a well-built body. It handles as a serious tool, with fast access to the main controls and support for data-back and flash accessories. It works with AF Nikkor lenses for autofocus across varied work.
On the used market, being fully electronic, it needs good batteries, so test AF, the meter and all exposure modes. Check shutter accuracy across the wide range, inspect the LCD for bleed, and look for perished light-seal and mirror-damper foam, common on this era. Also note the rear grip rubber can go sticky with age. Try loading and rewind. It uses standard cells rather than mercury batteries. AF Nikkor lenses autofocus; manual AI-S lenses meter with reduced support.
