Meyer-Optik's rare Exakta portrait prime — the Primoplan 75mm f/1.9 with bubble bokeh.
The Meyer-Optik Primoplan 75mm f/1.9 is a fast short-telephoto portrait prime from Meyer-Optik Görlitz, one of the most collectible and expensive lenses in the Exakta bayonet. It applied the Primoplan formula at a longer focal length, making it the maker's premium portrait glass. Original Exakta examples are rare and much sought after by users of vintage character lenses.
This is a manual-focus Exakta-mount lens with a 75mm focal length and a maximum aperture of f/1.9. It uses a five-element Primoplan optical layout scaled to the longer focal length. The aperture is set on the barrel and, on Exakta variants, coupled through the mount's internal lever. Filter thread, weight and other figures are omitted here where they cannot be confirmed for the specific Exakta build.
The Primoplan 75mm f/1.9 pairs the bubble bokeh of its 58mm sibling with the tighter framing and stronger separation of a 75mm portrait lens. Wide open, background highlights render as bright-rimmed discs and the edges swirl, while the subject stays sharp, giving portraits a distinctive three-dimensional look. It is above all a portrait lens chosen for that specific rendering.
This is a rare and costly collector lens, and original Exakta examples fetch very high prices, further raised by a modern reissue of the design. Inspect the glass thoroughly for haze, fungus, separation and coating wear, all of which affect both value and character. Confirm the aperture and focus operate smoothly. On mirrorless via an Exakta adapter it delivers its signature bubble bokeh on digital sensors.
