Nikon's first pro SLR with metered prism — the F Photomic, mechanical, Nikon F mount, 1962.
The Nikon F was Nikon's first system single-lens reflex, launched in 1959, and the Photomic version added a metered prism head. Introduced in 1962, the Photomic finder brought through-the-lens exposure reading to the F platform, aimed squarely at working professionals in press and reportage. The F established the Nikon F bayonet mount that continues on Nikon bodies to this day, giving the system its long service life.
This is a mechanical 35mm SLR using the Nikon F mount. It has a horizontal-travel titanium-foil focal-plane shutter with speeds to 1/1000 second plus B. The Photomic prism carries a CdS cell for external, non-TTL metering in this first version. Exposure is fully manual; the body fires mechanically and does not depend on a battery to release the shutter, the cell battery powering only the meter. The finder is interchangeable and the standard prism gives roughly full-frame coverage.
The F suits collectors and photographers who want a robust mechanical body for deliberate, manual shooting. It is heavy and built around modular finders, screens and motor drives, so it rewards users who value a system camera. The removable Photomic head means the meter can be swapped for a plain prism if the cell fails, keeping the body usable.
On the used market, check the Photomic meter, which relied on mercury cells; the original 1.35V PX-type batteries are no longer sold, so readings may be off without an adapter or recalibration. Inspect the shutter for capping and accurate speeds, look for prism desilvering and foam haze in the finder, and test film advance and rewind feel. Light-seal foam is minimal on this era body. F-mount lenses of the pre-AI period fit; later AI and AI-S optics may need care to mount.
