Cosina's budget mechanical K-mount SLR — the CT-1A, metered manual, 1982.
The Cosina CT-1A was a 35mm film SLR introduced in 1982 as a revision of Cosina's budget K-mount CT-1. Cosina produced many closely related bodies, some sold under other brand names, and the CT-1A continued the line's role as an affordable, simple SLR on the Pentax K bayonet.
It is a single-lens-reflex camera for 35mm film on the Pentax K mount. The CT-1A is a metered-manual SLR with TTL metering and a mechanically controlled focal-plane shutter, so it fires without a battery, the cell serving only the meter. Its controls are basic and conventional for a budget body.
It suits beginners and students wanting a low-cost mechanical body for learning exposure. The metered-manual approach and mechanical shutter are forgiving, and K-mount lenses keep the outfit inexpensive and easy to extend.
The CT-1A is cheap and common on the used market. Inspect the foam seals and mirror-damper foam, confirm the mechanical shutter fires across all speeds with no battery, and test the meter with a fresh cell. Check the film advance, rewind and screen; the plastic-heavy build is entry-level, so examine for wear, but the simple shutter is comparatively repairable.
