Konica's compact Hexanon normal — the 50mm f/2.4 in Leica Thread Mount.
The Konica Hexanon 50mm f/2.4 in Leica Thread Mount dates to 1997, from the period when Konica revisited its Hexanon rangefinder heritage. It is a comparatively modern screw-mount normal rather than an early vintage lens, made to a compact specification for use on L39 and adapted rangefinder bodies.
It is a manual-focus rangefinder-coupled lens with a 50mm focal length and a maximum aperture of f/2.4, an unusual value that keeps the barrel small. As a Konica Hexanon it carries the maker's normal-lens design tradition into a screw-mount package for rangefinder and mirrorless use.
At 50mm the lens gives a natural standard perspective for street, travel and general shooting, and the compact size makes it a discreet everyday normal. Hexanon normals are generally regarded for even, contrasty rendering, and this one sharpens up cleanly across the frame when stopped down.
Because it is a relatively modern lens, used copies are usually mechanically sound, but as with any used optic check for clear glass, smooth focus and a crisp aperture, plus any cleaning marks or haze. It adapts to Leica M with an LTM-to-M ring and to mirrorless cameras via a simple adapter for compact everyday shooting.
