What are Zingraff Paris opera glasses?

Zingraff Paris opera glasses are small handheld binoculars linked with theatre culture in 19th-century France. They were designed for indoor viewing, often used in venues such as the Palais Garnier in Paris after its opening in 1875. These glasses usually feature a compact body, short barrels, and a central focusing wheel. Zingraff pieces became known for decorative finishes, including mother-of-pearl, enamel, and gilt brass. Unlike field binoculars, their magnification stayed modest, often around 2x to 4x, which suited close viewing rather than long-distance observation. Collectors place value on original cases, which were often lined with velvet or silk. Some examples from the late 1800s have sold for €150 to €600, depending on condition and decoration. The brand reflects a period when attending opera was as much about social display as the performance itself. Opera glasses were used to observe both the stage and other audience members, making them part optical tool and part fashion accessory.
