Nikon F-401AF1987

History

Nikon's path to mass-market AF moved in clear steps. The F-301 (N2000, 1985) motorized film advance but did not offer autofocus. The F-501 (N2020, 1986) was Nikon's first mainstream AF body but was priced above the entry tier. The F-401AF (N4004, 1987) brought AF and matrix metering down to the lowest price point in the Nikon lineup, competing directly with Canon's EOS 650 and Minolta's Maxxum 5000i.

The F-401AF introduced matrix metering to Nikon's cheapest SLR - a feature significant enough that Nikon advertised it specifically. The AF system used the same screw-drive coupling as the F-501 and F4, meaning any AF Nikkor lens with the internal focus motor coupling worked correctly. The F-401AF was succeeded by the F-401s (N4004s), which offered modest improvements to AF speed and handling without changing the fundamental architecture. The F-401x (N5005, 1991) followed with further revisions.

Canon's simultaneous introduction of the EOS 650 (1987) with a dedicated EF mount and in-lens AF motors demonstrated a competing architecture that would ultimately prove more scalable, but at the time both systems targeted the same buyer: someone who wanted autofocus without thinking deeply about it.

Why It Matters

The F-401AF matters primarily because of what it plugs into: the Nikon F-mount ecosystem. Every AI, AI-S, and AF Nikkor lens from 1977 onward works on this body at full metering capability. AF Nikkor lenses autofocus; AI-S lenses focus manually with correct aperture-priority, shutter-priority, and program exposure. The camera itself is utilitarian - polycarbonate construction, no weather sealing, consumer ergonomics - but the lens compatibility makes it a durable entry point.

For 2026 users buying into film, the F-401AF is among the cheapest bodies that provide autofocus, matrix metering, and full compatibility with the vast secondhand market in AF Nikkor and AI-S glass. It is not the camera to choose if build quality or manual control depth matters; it is the camera to choose if budget is the constraint and the F-mount lens library is the goal.

Lenses & Accessories

Nikon F mount. AF Nikkor lenses with screw-drive coupling autofocus via the in-body motor; AF-S lenses mount but will not autofocus (no in-body motor can drive them; AF-S requires in-lens motor). AI and AI-S Nikkor lenses operate in full-aperture metering mode with manual focus. Pre-AI (non-AI) lenses can mount but may damage the AI coupling ridge; check compatibility before attempting.

Most commonly sold as a kit with the AF Zoom Nikkor 35-70mm f/3.3-4.5 or AF Nikkor 50mm f/1.8. Built-in pop-up flash handles basic fill and low-light snapshots; compatible with Nikon SB-series Speedlights via the hot shoe for TTL flash control.

Sample Photographers / Notable Use

• Sold primarily through mass-market retail channels - department stores, camera chains, mail-order catalogs - rather than professional dealers.
• Used by consumers and photography students as an entry point to the Nikon F-mount system in the late 1980s and early 1990s.
• Not associated with specific professional or editorial photographic work; the F-401AF is a volume-market camera whose significance is demographic rather than artistic.
• Frequently bundled with 35-70mm AF zoom kits in department-store photography promotions, 1987-1990.
