Pentax's advanced manual K-mount SLR — the KX, match-needle TTL with mirror lock-up, 1975.

The Pentax KX of 1975 was part of the first K-bayonet generation that replaced the M42 screw mount, sitting as the higher-specified manual body of the original K-series. It launched alongside the KM and the automatic K2 as Pentax introduced the K lens mount that would run for decades. It offered a well-equipped manual camera with a match-needle meter.

This is a 35mm film SLR using the Pentax K bayonet, giving open-aperture TTL metering with K-mount lenses. It has a horizontal cloth focal-plane shutter running from 1 second to 1/1000 plus B, and a fixed eye-level pentaprism with an instant-return mirror, a mirror lock-up and a depth-of-field preview. Metering is centre-weighted match-needle TTL for manual exposure; there is no auto mode. The shutter is largely mechanical, with the battery powering the meter, so the camera can fire without power.

The KX suits students, documentary and portrait photographers and anyone wanting a well-featured manual K-mount body with mirror lock-up and preview. It handles smoothly with a bright finder and a clear match-needle display, offering more control than the base KM. It sits at the start of the long-lived K system with its broad, still-available lens range.

As a mid-1970s body, checks matter. Inspect and expect to replace perished foam light seals and mirror-damper foam. Test the cloth shutter for pinholes, capping and even speeds, and try the mirror lock-up and preview. The meter needs a battery, and this later design suits modern silver-oxide cells rather than the mercury type of the Spotmatics. Check the pentaprism for desilvering or foam haze, and test the advance and rewind. The mechanical shutter still fires with a dead battery, and the K mount keeps lens choice wide.
