Linhof
Linhof is a German company, founded in Munich in 1887 by Valentin Linhof. The company is well known for making premium rollfilm and large format film cameras. Linhof initially focused on making camera shutters and developing the first leaf shutter, which became part of Compur.
Nikolaus Karpf, who entered the company in 1934, designed the first Technika model, the world's first all-metal folding field camera, the same year. Revised models of the Technika are still in production.
Today Linhof is the oldest still-producing camera manufacturer in the world after Gandolfi and Kodak stopped their production.
