The Diana Instant Square is an instant camera from Lomography styled to resemble and function similar to the Diana, but using Instax Square film format. The camera is notable as it is the first Instax camera which can use an external flash unit (either the Diana F+ flash unit or any hotshoe flash). It also shares the interchangeable lens mount of the Diana F+, allowing it to use any of the Lomography Diana F+ lenses. It however does not support the original Diana F+ Splitzer. Like all of Lomography's other Diana series cameras, it is fully manual and lacks any metering. Unlike the Diana F+ the camera has a detachable viewfinder, which can be replaced for different lenses. -camera-wiki.org
