Adox POLOmat 1S (1962–1964)

A selenium meter that still works after 60 years, if the cell hasn't given out.

Overview

The Adox POLOmat 1S measures light with no batteries. It has no rangefinder and no interchangeable lenses. It's a 35mm viewfinder camera from the early 1960s, built in Wiesbaden, Germany, during the last stretch of Adox's own camera production before the brand shifted entirely to film. Its chrome-and-leather body is modest. What sets it apart from the other cameras in the Polo line is the selenium meter, a long, curved strip wrapped around the lens. It turns light into exposure readings with no power source beyond ambient light.

The POLOmat 1S was positioned as a step up from the basic Polo models. It shared the 45mm f/2.8 Schneider-Kreuznach Radionar L lens found on higher-end variants. The glass uses lanthanum oxide, a rare-earth element added to increase refractive index and reduce aberrations. The shutter is a Prontor 500 LK with speeds from 1/15 to 1/500 second, plus Bulb and self-timer. That makes it a capable little package for daylight shooting. The meter coupling works like this: you set film speed on the top plate, then match two needles in the meter window. One is driven by light, the other by your selected shutter speed and aperture. When they align, you're correctly exposed.

But don’t mistake this for a precision instrument. The POLOmat 1S is charmingly analog in every sense, including its quirks. The plastic-bodied construction—common for mid-tier 35mm cameras of the era—gives it a lightweight, almost toy-like feel, though the metal top and bottom plates lend a surprising amount of rigidity. The film advance lever is short and stiff, and the shutter release has a mushy, indistinct throw that makes it hard to confirm exposure without looking at the frame counter. Worse, the camera offers no mechanical feedback to confirm the shutter fired—just a faint click that can vanish in street noise. That’s unnerving the first few rolls, until you trust the interlock system that prevents double winding. And yes, the lens barrel is mostly plastic too, which means focus and aperture rings can stiffen or crack over time, especially if they’ve spent decades in attics or damp drawers.

Key Features

The Selenium Meter That Outlived the Company

The defining feature of the POLOmat 1S is its selenium light meter: no batteries, no electronics, just a photovoltaic cell generating current from light. The long, curved strip is mounted around the front of the lens to capture as much light as possible. It drives a needle in the top-plate meter window, which you match against a second needle set by your chosen shutter speed and aperture. When aligned, exposure is correct. It works well in consistent daylight, but selenium cells degrade over time, losing sensitivity or failing entirely. On surviving examples, the meter often still moves, but sluggishly, or only in bright sun. A non-working meter doesn't cripple the camera. You can still use it with an external meter or the Sunny 16 rule.

Schneider-Kreuznach Glass in a Budget Body

A Schneider-Kreuznach Radionar L lens on a camera this modest is a surprise. Schneider was (and is) a name associated with precision optics, and the Radionar series, especially the "L" variant with lanthanum-doped glass, was designed to deliver sharp, contrasty images with minimal flare. In practice, the 45mm f/2.8 on the POLOmat 1S gives results that punch above the camera's weight. Images are clean in the center, with a gentle fall-off into softness at the edges, especially wide open. Stopped down to f/8 or f/11, it resolves fine detail with a film-like texture. It isn't clinical, but it's honest. The lens lacks coatings by modern standards, so backlit scenes can produce haze or ghosting. Used with modern high-ISO films, it can give expressive results in moody or textured scenes where absolute sharpness isn't the goal.

Scale Focus and the Art of Guessing

There's no rangefinder and no through-the-lens viewing. You get a simple optical viewfinder with parallax lines and a distance scale on the lens barrel. You estimate distance, turn the focus ring, and hope. At f/2.8 and 1 meter, depth of field is razor-thin, so misjudging by even 10cm can blur your subject. You learn to pace off distances, use hyperfocal tricks, or just accept the softness. The plastic focus ring doesn't help. On many examples it's stiff or gritty, suggesting dried lubricant or worn threads. A CLA (clean, lubricate, adjust) can restore smoothness, but it's a delicate job given the lens's mixed plastic-metal construction. For street or travel use in daylight, with film speeds between ISO 50 and 100, it does the job.

Historical Context

The POLOmat 1S arrived in 1962, when 35mm cameras were rapidly evolving from luxury items to mass-market tools. Adox, originally a film company founded in 1860, had dabbled in cameras since the 1930s, initially by repurposing Wirgin designs after the Nazi seizure of Jewish-owned businesses. By the 1960s it was trying to carve a niche in a crowded field. The POLO series was Adox's answer to compact, easy-to-use 35mm cameras like the Kodak Retina, Zeiss Ikon Contessa, and Braun Paxette. The POLOmat 1S sat near the top of that lineup, above the basic Polo 1 and Polo 1S, with the selenium meter as a premium feature. It was introduced alongside the POLO 1S at the 1961 Photo-Cinema Salon in Paris.

Adox was already on borrowed time as a camera maker. By the mid-1960s, DuPont had acquired the company and shifted focus to X-ray and industrial films. Camera production ended in 1965, and the Adox name faded until its revival in the 2000s by Fotoimpex as a boutique film brand. That makes the POLOmat 1S one of the last true Adox cameras. It wasn't revolutionary, but it was competent, honest, and modestly priced. It competed not with Leicas or Nikons, but with mid-tier European and Japanese models that prioritized convenience over precision. It offered a selenium meter and a Schneider lens in a pocketable form.

Collectibility & Value

Today, the POLOmat 1S is a quiet collector's item, rarely discussed. It's not a showpiece like a Contax or a Leica, but it has a cult following among photographers who appreciate understated engineering and passive metering. Prices reflect its obscurity: working examples in good condition typically sell for $50 - $80, while mint or boxed units might reach $120 - $140. Non-working meters drag value down, but not drastically. Most buyers expect some degradation after 60 years.

Common failures include degraded selenium cells (the most frequent issue), stiff or frozen focus/aperture rings, and worn film advance mechanisms. The plastic tripod socket is fragile, and overtightening can strip it. The film pressure plate, though metal, can warp if the back is forced shut. When buying, test the shutter at all speeds, check that the film advance fully cocks the shutter, and inspect the meter needle for movement in daylight. Even if the meter doesn't read accurately, its presence adds historical value. A full CLA from a technician experienced with vintage German shutters can run $75 - $120, which may exceed the camera's worth unless it's a sentimental or display piece.

For shooters, the POLOmat 1S is best suited to sunny-day photography with ISO 50-100 film. It's light enough for travel, simple enough for beginners, and distinctive enough to spark conversation. It won't replace a rangefinder or SLR, but it's a low-stakes, battery-free film camera. Don't expect lab-grade accuracy.
