Ludwig or Ernst Ludwig was a German optical company based at Lausa, a small town near Dresden.
The town of Lausa merged with the neighbour town of Weixdorf in 1938. Some prewar lenses were thus marked Ludwig Lausa Dresden.
Ludwig made entry level lenses, often with three elements. After the war, they were offered as a low price alternative to the Carl Zeiss Jena or Meyer lenses. In 1972 it was absorbed in VEB Kamerafabrik Freital, and in 1980 it fell under VEB Pentacon.
Some trademarks used for Ludwig lenses include:
- Auxanar (simple triplet, enlarger lens)
- Cosmar (five element triplet with cemented first and third groups)
- Kosmar (four element triplet with cemented front group)
- Meritar (simple triplet or a Tessar type)
- Victar (simple triplet)
Ludwig was not a camera maker, but rather a lens maker. Cameras equipped with a Ludwig lens include:
