Pentax Super-Takumar 85mm f/1.9

Set the Super-Takumar 85mm f/1.9 next to a Jupiter-9 85mm f/2, the cheap Sonnar everyone else adapts for vintage portraits, and the gap shows up in the first frame. The Jupiter-9 glows: soft wide open, low in contrast, the background swirling into that dreamy Soviet bloom. The Takumar is the disciplined version of the same idea. It holds the eyelashes sharp at f/1.9 while the background still melts, and it does it with a cleaner, more neutral color. If the Jupiter-9 is a mood, this is a tool.

Asahi built it during the Super-Takumar run, before the multicoated SMC line, so it wears a single coating. That cuts two ways. Aim it at a window or a low sun and you get veiling flare and a contrast drop a modern lens would shrug off; a hood takes most of that back. Shoot it wide open into soft backlight and the same trait gives skin a faint bloom that plenty of portrait shooters now fake in software. Stop down to f/2.8 or f/4 and the glow tightens and the frame turns genuinely crisp.

The build is the part nobody argues about. All metal, a focus ring damped like a bank vault, and the Super-Takumar A/M switch on the barrel. Bolt it to a Sony or Fuji body through an M42 adapter and you flip that switch to M so the aperture actually closes when you turn the ring, since there is no camera pin to trip it. The 58mm filter thread is shared with several other Takumars, so one set of filters can cover more than one lens.

f/1.9 was the quiet edge. The Sonnar-type 85s it grew up against, the Zeiss and the Jupiter-9, topped out at f/2, so the Takumar handed you a hair more speed. The rendering is its own thing, less the high-contrast Sonnar bite and more a gentle, sharp-where-it-counts draw that flatters faces. For available-light portraits, the kind you shoot in a doorway at dusk, that plus the 85mm length is the combination you want. Meter off the face in open shade and let Zone Light Meter set where it lands on the curve; wide open on a thin slide your latitude is maybe a third of a stop, so you want that reading nailed before the light drops.

The honest catch is what it costs now. This one was overlooked for years and the going rate has crept up well past bargain territory, so these days you tend to pay near portrait-lens money for a fifty-year-old single-coated optic. If you only want the look, a Jupiter-9 or an adapted Canon FD 85mm f/1.8 gets you most of the way for less. People hunt the Takumar anyway, partly for how it draws, partly because a clean copy feels better in the hand than almost anything built since.
