Zenit F-21 (KGB-camera, belt)

The Zenit F-21, colloquially known as the "KGB-camera, belt," is a clandestine 35mm camera introduced in 1977. Disguised as an ordinary belt buckle, it was designed for covert surveillance operations, allowing operators to discreetly capture images without raising suspicion. This device exemplifies the Cold War era's focus on espionage technology, prioritizing concealment over photographic performance. Featuring a fixed-focus lens and a simple shutter mechanism, the F-21 offered very basic imaging capabilities, sufficient for its intended low-resolution reconnaissance tasks but far from the standards of contemporary consumer cameras.
