Lens OverviewKonica 300mm f/4.5 AR

The Konica 300mm f/4.5 Hexanon EE is a manual focus prime telephoto lens built for the Konica AR mount system. Designed for full-frame SLR cameras, this vintage prime delivers a fixed 300mm focal length with a maximum aperture of f/4.5, making it a capable option for telephoto shooting of distant subjects. As a manual focus only lens, it demands a hands-on shooting approach that many photographers find rewarding for deliberate, considered work.

The lens accepts 77mm filters, a generous thread size that aligns with many modern filter systems, making it practical for photographers who shoot with polarizers or ND filters. Weighing in at 850g, it carries a solid, substantial feel typical of well-built vintage glass. With no image stabilization on board, steady technique or a tripod is advisable at this focal length, especially in lower light conditions.

The Konica AR mount is a legacy system, so adapters are typically required to use this lens on modern mirrorless or DSLR bodies, opening it up to a wide range of contemporary camera systems for those interested in exploring vintage optics.
