Konica Auto-Reflex — the SLR that flips formats mid-roll.
A genuinely clever classic: switch from full-frame to half-frame (and back) with a lever, even in the middle of a roll. Paired with the underrated Hexanon 52/1.8—sharp, smooth rendering, and a joy to focus.
What’s working
Shutter fires across speeds
Aperture blades snappy
Format selector moves/locks correctly
Advance, self-timer, and controls operate as expected
Viewfinder bright and usable
Optics
Hexanon glass presents clean—no fungus or haze seen; only normal dust from age.
Coatings intact; no obvious scratches noted
Cosmetics (see photos)
Honest user wear throughout: brassing, scuffs, edge rubs
Oxidation around eyepiece ring; typical marks and residue on baseplate
Leatherette intact; trim shows age-appropriate patina
Notes
Meter not fully evaluated; battery check switch responds, but accuracy not verified. Camera was originally designed for a 1.35V mercury cell—use a modern equivalent/adapter (e.g., Wein cell) if you plan to meter in-camera.
