Pentax's mechanical-only K-mount SLR — the KM predecessor to the K1000.
The Pentax KM launched in 1975 as one of the first Pentax K-mount SLRs — the predecessor to the K1000. Fully mechanical with match-needle metering. The KM was the mechanical base model in the original K-series.
Same basic concept as the K1000 — fully mechanical with match-needle metering. The KM predates the K1000 and was made only in Japan (later K1000 production moved to other factories). K-mount — all K lenses.
Pentax K mount. Fully mechanical. Match-needle metering. Made in Japan only — the KM predates the K1000. The original K-mount mechanical base model.
Available used very cheaply — less well-known than the K1000. Made in Japan — potentially better build than late K1000 production. For K-mount film photography. The KM is essentially a proto-K1000.
