Brightness range for autofocus/focus aid operation: Approx. EV 4~EV 20 (at ASA/ISO 100)
Focus lock buttons: Two buttons provided on AF-Nikkor lens barrel; either locks lens distance setting during autofocus operation.

Focus information display: Visible in the viewfinder via red LEDs; two red arrows light up to indicate correct focus in autofocus/focus-aid operation, right or left hand arrows indicate out-of-focus image (too near or too far), red X glows to when autofocus/focus-aid is impossible or subject is out of focus to a great extent.

Exposure control system:

Aperture priority automatic exposure or manual override and backup mechanical control
Through the lens, full aperture metering via silicon photo diode (SPD) with Centre-Weighted metering pattern and metering circuits incorporated into the camera body
Meter works with all viewfinders.

Metering range: EV 1 to EV18 at ASA/ISO 100 with f/1.4 lens or EV 3 to EV 20 at ASA/ISO 100 with f/2.8 lens.
Shutter: Horizontal-travel, titanium focal plane shutter
Shutter speeds:

Auto: electro-magnetically controlled stepless speeds from 8 to 1/2000 sec.
Manual: quartz/electro-magnetically controlled discrete speeds from 8 to 1/2000 sec., plus B and X (1/80 sec.)
Mechanical: T setting on shutter speed dial and 1/60 sec. when using backup mechanical release lever.

Exposure information display: Visible in the viewfinder via LCD; on auto, discrete shutter speed closest to automatically selected speed is displayed, overexposure indicated by +2000 and -8 indicates underexposure; on manual, M appears with + or - indicating over or underexposure and -+ correct exposure; aperture in use is also shown through aperture direct readout (ADR) window.
Shutter release button: Electro-magnetically releases shutter; initial pressure on shutter release button switches on meter and autofocus/focus-aid function (after power switch is turned on), meter and autofocus/focus-aid function then remain on for 16 sec. after finger is taken off button.
Backup mechanical release lever: Trips shutter at 1/60 sec. regardless of shutter speed dial setting except at T; used when batteries are dead.
Viewfinder: Interchangeable eyelevel pentaprism type AF Finder DX-1 as standard; 0.8X magnification with 50mm lens or 1.3x with 80mm lens, both lenses set at infinity; approx. 92% frame coverage; five other types available.

Film speed range: ASA/ISO 12 to ASA/ISO 6400
Exposure compensation dial: (+/-) 2 EV compensation is possible in one-third increments
Exposure memory lock button: Operates on auto to electronically lock in shutter speed
Auto flash control system: TTL direct flash control governs output of Nikon dedicated flash unit using camera's SPD sensor; effective ASA/ISO range from ASA/ISO 25 to ASA/ISO 400
Accessory shoe: Special Nikon type located at base of rewind knob; has hotshoe contact, ready light contact and TTL flash output control contact; accepts Nikon SB-12 or SB-16A shoe-mounting electronic flash unit or TTL direct flash output control from SB-11 and SB14 for TTL direct flash output control using camera's SPD metering cell.
Sync terminal: Threaded type provided for off camera or multiple flash photography.
Flash synchronization: Speeds of 1/80 sec. (X) or slower with electronic flash; with Nikon dedicated flash unit, flash sync is automatically set to 1/80 sec. when shutter speed dial is set at A or 1/125 sec. or above; at slower speeds, shutter fires at the speed set.
Flash ready-light: Visible in the viewfinder; LED lights up when Nikon dedicated flash unit is completely recycled or blinks to warn of insufficient light output, improper flash connection, or improper ASA/ISO setting.
Film advance lever: Wound in single stroke or series of strokes with 30° standoff angle and 140° winding angle.
Automatic film advance: Possible with optional Motor Drive MD-4
Frame counter: Additive type, self-resetting; for blank exposures before frame one, shutter speed automatically set to 1/80 sec. with shutter speed dial set at A or 1/125 sec. or above.
Film rewind: Via folding crank and rewind button in base plate
Self-timer: Quartz timed 10 sec. delayed exposure; LED blinks at 2Hz for first 8 sec. then at 8 Hz for last 2 sec.

Important!

The Nikon F3AF is an AI-type (Automatic Maximum Aperture Indexing) camera which performs full-aperture metering with AI-type lenses. The aperture ring of these lenses has a meter coupling ridge and a meter coupling shoe containing two holes. Almost all lenses now manufactured by Nikon are of the AI-type. However, please confirm whether or not your lens is AI before mounting it with the F3AF. Note that the 'AI' or 'AI-S' mark on the cover of the instruction sheet or book provided with AI-Nikkor lenses is your assurance that the lens offers the AI feature. All Nikon Series E lenses have the AI feature but do not have a meter coupling shoe.

To attach an AI-type lens to the camera body, follow the directions provided in the BASIC OPERATION section of this instruction manual. If the lens is a non-AI type stop down exposure measurement is required with the camera body's meter coupling lever locked up. Note: The modification, at reasonable cost of most non-AI Nikkor lenses having both an automatic diaphragm and meter coupling shoe, is available for the convenience of Nikkor lens users. For further information concerning lens modification, please contact your local authorized Nikon dealer.
