Meyer-Optik's budget Exakta triplet — the Domiplan 50mm f/2.8 with a soft vintage rendering.
The Meyer-Optik Domiplan 50mm f/2.8 is a low-cost standard prime from Meyer-Optik Görlitz, offered in the Exakta bayonet and widely fitted to budget East German cameras as a kit lens. Its Exakta and screw-mount versions date from around 1961. The Domiplan was made in large numbers as an entry-level normal, which makes it one of the most common vintage standards of its era.
This is a manual-focus Exakta-mount lens with a 50mm focal length and a maximum aperture of f/2.8. It uses a simple three-element triplet optical layout, which keeps the design cheap and light. 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 Domiplan's simple triplet gives a soft, gentle rendering wide open that becomes acceptably sharp in the centre when stopped down, with out-of-focus areas that can turn nervous or busy with bright background detail. Users prize it for this affordable soft character rather than clinical sharpness, and it suits relaxed portraits, street and general shooting where a distinctive vintage look is wanted.
Domiplans are cheap and plentiful on the used market, which makes them a common first vintage lens. Their weak point is the aperture mechanism, which was economically built and often sticks, so confirm the blades snap shut cleanly and are free of oil. Check the glass for haze and fungus and the focus for smoothness. On mirrorless via an Exakta adapter it is an inexpensive way to try the triplet look.
