The Konica FS-1 (1979) was the **first 35mm SLR with a built-in motor drive** — a feature that wouldn't become standard until the late 80s with bodies like the Canon EOS-650. Konica AR bayonet mount, aperture-priority AE, electronic vertical metal shutter to 1/1000s, TTL CdS metering. Powered by 4 AA batteries (the integrated motor drive needed serious power). The body is awkwardly shaped — the motor drive lives in the bottom plate, making the camera taller than most SLRs.

Released 1979 as Konica's volume-seller SLR. Production ran 4 years until 1983. The FS-1 was followed by the FS-1N (refined cosmetics) and the consumer-tier FT-1 (1983) and TC-X (1985). Konica exited the 35mm SLR market in the early 90s and merged with Minolta in 2003.
The FS-1's built-in motor drive concept was revolutionary for 1979 but commercially unimportant — it competed against Canon AE-1 / A-1 and Minolta XD-11 / X-700 bodies that weighed less and cost less. Konica's quirky decision to integrate the motor drive made the body a curiosity that historians of camera design appreciate, but most working photographers never adopted it.
For 2026 buyers, the FS-1 is a cheap, weird piece of camera history at $80–200 used. The Konica Hexanon AR-mount lens system is excellent and undervalued — the 50/1.7 AR and 40/1.8 AR are sharp Hexanons with character.
Konica AR mount: Hexanon AR lenses (50/1.7, 50/1.4, 40/1.8, 24/2.8, 28/3.5, 85/1.8, 135/3.2, etc.). The AR mount is a discontinued ecosystem; used Konica AR lenses are reasonable to find but not as plentiful as Canon FD or Pentax K.
