The Zorki 4K (1972) is a refinement of the Zorki 4 (itself based on the Leica II/III lineage). The "K" indicates the **lever film advance** — earlier Zorkis used a knob like a Leica Barnack body, requiring two-handed winding. The 4K adds a single-stroke lever like a modern rangefinder. Mechanical horizontal-cloth shutter to 1/1000s, M39 LTM mount (compatible with all Leica screw-mount and Soviet LTM lenses), no meter, manual exposure. Built in the KMZ (Krasnogorsk Mechanical Plant) factory near Moscow.

The Zorki line started 1948 (Zorki 1, a near-direct Leica II copy). Iterations through Zorki 5, 6, and the Zorki 4 (1956), which refined the design but kept knob film advance. The Zorki 4K (1972) added the lever and updated cosmetics. Production ran 8 years to 1980 — 525,000 units.
For Leica LTM-system buyers on a budget, the Zorki 4K is the better choice over the FED-2 because of the lever advance — lever winding is significantly faster and more intuitive than knob winding. The Zorki 4K's shutter goes to 1/1000s (vs FED-2's 1/500s). The trade-off is build-quality variance (Soviet QC) and the lack of strap lugs on some bodies.
For 2026 buyers at $70–180, the Zorki 4K is the most-recommended Soviet LTM rangefinder for daily use. Pair with a Soviet Industar-50 50/3.5 (cheap, sharp) or Jupiter-8 50/2 for an excellent budget LTM kit.
M39 / LTM mount: same as Leica IIIf, FED-2, etc. Soviet lenses (Industar, Jupiter, Helios), Leica LTM (any era), modern Voigtländer LTM all mount and rangefinder-couple.
