Meyer-Optik's budget Exakta normal — the Tessar-type Primotar 50mm f/3.5 standard prime.
The Meyer-Optik Primotar 50mm f/3.5 is a standard prime from Meyer-Optik Görlitz, offered in the Exakta bayonet as an economical normal lens. The Primotar name marks a Tessar-type four-element design, and this slower f/3.5 version served as a budget standard for Exakta bodies. It gave buyers a simple, compact normal lens at a lower price than the faster standards.
This is a manual-focus Exakta-mount lens with a 50mm focal length and a maximum aperture of f/3.5. It uses a Tessar-type four-element optical layout. 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 Primotar 50mm f/3.5 gives the crisp centre and clean rendering typical of a good Tessar-type standard, sharpening further as it is stopped down. Its modest maximum aperture makes it a general-purpose normal for daylight street, travel and landscape work rather than a low-light or shallow-depth lens. Contrast and colour are in the classic East German mould.
Used Primotar standards are among the more affordable Meyer-Optik lenses and appear fairly regularly. Inspect the glass for haze, fungus and separation, and confirm the aperture blades are dry and the ring clicks. Check the coatings for cleaning marks and test the focus for smoothness. On mirrorless via an Exakta adapter it makes a compact, inexpensive vintage normal lens.
