Konica's AR short tele — the 100mm f/2.8 Hexanon, a compact portrait prime.
The Konica Hexanon AR 100mm f/2.8 was a short telephoto prime for the Konica AR bayonet on the Autoreflex system. The 100mm focal length is a classic portrait and short-tele length, and this Hexanon covered that role in the AR line as a compact, moderately fast telephoto.
This is a manual-focus Konica AR lens with a 100mm focal length and a maximum aperture of f/2.8. It is a short telephoto prime. Optical construction, filter thread and minimum focus distance are not verified here and are omitted rather than invented so the specification stays trustworthy.
A 100mm f/2.8 gives the compressed perspective and comfortable working distance that make it a natural portrait lens, isolating a subject against a smoothly blurred background. It also suits candid, detail and travel work where a modest reach and easy handling are wanted.
The 100mm Hexanon is a well-regarded portrait tele that turns up at reasonable prices. Check the elements for haze, fungus and coating marks, confirm the aperture blades are dry and snap cleanly, and feel the focus ring for even action. It adapts well to mirrorless via an AR adapter for manual portrait work.
