The Konica IIIM (1959) is a refined version of the IIIA and the final camera in Konica's fixed-lens coupled-rangefinder 35mm line. It adds a selenium light meter to the IIIA's formula while retaining the same **Hexanon 48mm f/2** six-element lens, Seikosha MXV leaf shutter, coupled rangefinder, and **1.0x lifesize viewfinder**. The selenium cell does not require a battery and never will; readings are taken separately and set manually on the shutter/aperture controls. The IIIM marks the end of an era: Konica subsequently moved toward fully automatic exposure with the Auto S series.

The IIIM followed directly from the IIIA (1958). Where the IIIA had no metering at all, the IIIM integrated a selenium cell on the front face of the body. The meter is uncoupled - it gives an EV or aperture/shutter recommendation that the photographer dials in manually, similar to the approach used by the Leica M5's meter being added later to an otherwise manual system. After the IIIM, Konica shifted to the Auto S (1963) and Auto S2 (1965), which featured auto-exposure and a new 45mm Hexanon lens. The IIIM is consequently the last fixed-lens Konica rangefinder in the classic body style.
The IIIM occupies a narrow collector niche: the IIIA without a meter is already sought after; the IIIM adds selenium metering in the same body without compromising the battery-free mechanical operation. Selenium meters degrade over decades, so many surviving IIIMs have a dead or unreliable meter cell - this is worth verifying before purchase, though the camera functions perfectly without it. The Hexanon 48/2 glass is the same optically excellent formula found on the III and IIIA.
