Konica Auto-Reflex

Put it next to a Pentax Spotmatic from the same years and the difference is immediate. The Spotmatic was lighter, screw-mount, and stop-down metered, the camera every student bought. The Auto-Reflex went the other direction. It is heavy, it bayonets, and it does something almost nothing else from 1965 could do: it sets the aperture for you. You pick a shutter speed, the meter reads the scene, and the lens follows. People still hunt one down for exactly that.

The build is the first thing you notice picking one up. It has real density to it, the kind of cold metal weight that makes the camera feel like it will outlive you. The Konica AR mount is a proper bayonet at a time when half the market was still threading lenses on, and the standard 52mm f/1.8 Hexanon is sharp enough that the body's heft feels earned. The finder is bright for the era, a plain ground glass with a microprism center, no split image. You frame, you turn the speed dial, you watch the needle settle, and you fire.

The meter is a CdS cell, and it does not just advise you, it drives the automation. This is shutter-priority: you set the speed, the cell reads the light, and the body swings the aperture to match rather than asking you to line up two needles by hand. When it works it is genuinely useful. The shutter is a cloth focal-plane unit running from a full second down to about 1/500, with flash sync near 1/120, which is quick for a horizontal-travel curtain of this vintage. The sound is a flat mechanical clack, no electronic whine, because the speeds are mechanical and only the meter wants a battery.

Its real signature is the half-frame switch. A control on the body crops the gate to 18x24 mid-roll, and the finder masks down so you actually see the crop. Shoot a standard 36-exposure roll entirely in half-frame and you net around seventy-two shots, or you flip the switch partway through and mix full and half on the same load. It was a rare trick even for Konica in this generation; the later Autoreflex T quietly dropped it. That switch is half the reason these are collectible now.

The honest weakness is the meter cell. These are sixty years old, the CdS reading drifts, the seals go gummy, and the original mercury battery is long gone, so the automation you bought the camera for is the part most likely to give you a bad reading. Treat the needle as a starting point and meter the scene yourself. An incident or spot reading from the Zone Light Meter app gives you the exposure an aging cell can no longer be trusted to find, then you set the speed and let the lens follow or dial the aperture by hand. Place your shadows where you want them rather than chasing a tired needle.

Today it sits in the cheap-and-overlooked tier, cross-shopped against the Spotmatic and early Minoltas, usually going for less than either despite the better mount and the half-frame trick. People avoid it because dead meters scare them, and Hexanon glass is harder to stumble across secondhand than the Takumars that flooded the M42 world. The ones who buy it anyway tend to hang onto it.
