Cosina

Cosina Co., Ltd. is a Japanese company primarily known for manufacturing photographic lenses, optical glass, cameras, and other optical-related products. Founded in 1959, the company initially produced optical components for other manufacturers. Over time, Cosina expanded its operations to include the production of complete camera bodies and lenses, both under its own brand and for other well-known camera brands.

Cosina has a long history of collaboration with other camera and lens manufacturers. They are known for producing high-quality, often relatively affordable, lenses, particularly manual focus lenses, for various camera mounts, including Canon EF, Nikon F, Sony E, Micro Four Thirds, and Fujifilm X. These lenses are often valued for their build quality, optical performance, and tactile feel, appealing to photographers who appreciate manual control and a more traditional shooting experience.

In addition to manufacturing lenses, Cosina has also been involved in the production of camera bodies, most notably the Voigtländer Bessa series of rangefinder cameras. While they no longer produce these cameras, they remain a significant part of Cosina's history and contribute to the company's reputation among photography enthusiasts.

Cosina's product line generally focuses on providing photographers with durable, high-performing optics at a competitive price. Their consistent quality and collaborative business model have allowed them to remain a relevant player in the photographic industry for several decades.
