Petri Camera Co. was a smaller Japanese maker, producing budget rangefinders and SLRs through the 60s and 70s. The Petri 7 (1961) introduced the line; the 7s (1963) refined it. Production ran 10 years until 1973 when Petri exited the RF market. Petri itself went bankrupt around 1977.
For 2026 buyers, the Petri 7s is the cheapest fixed-lens 60s rangefinder you can buy. Used at $40–120 — significantly less than Canonet QL17 or Yashica Electro 35. The selenium meter requires no battery, which is genuinely useful for travel. The lens is mediocre by Canonet/Konica standards but adequate for casual shooting.
The trade-off is build quality (lower than Canon/Yashica), service availability (essentially zero), and parts (zero — Petri died).
Lens fixed. Standard hot/cold-shoe flashes via leaf shutter all-speed sync.
