The Asahiflex IIB was released in 1954. With the IIB, a key advance was made, the quick-return mirror. It was the world's first SLR camera with an instant return mirror. [1] The problem of mirror black-out was one of the main problems with prior SLR designs, greatly reducing usability and leading to the greater popularity of the rangefinder.
A special feature of this camera series was the exchangeable viewfinder unit. A simple top-viewfinder and a pentaprism finder were available. In 1960 the Model B had a name change and became the Edixa-Mat Flex Model B, the word Reflex being shortened to Flex, and it featured shutter speeds from 1/25 to 1/1000 of a second, the instant return ...
The digital single-lens reflex camera has largely replaced the film SLR for its convenience, sales, and popularity at the start of the 21st century. These cameras were the marketing favorite among advanced amateur and professional photographers through the first two decades of the 2000s.
The mirrorless interchangeable-lens camera achieves the same result by providing the photographer with a digitally captured image. The twin-lens reflex camera provides both a viewfinder image by reflecting the image onto ground glass and an image through another lens to the film. The image exposing the film is not reflected.

The camera utilizes a three lens turret with three aluminum Arri lens mounts (later 35 IIC/B with one stainless steel bayonet mount and two aluminum Arri mounts), and is capable of frame rates up to 80 frames per second with an accessory speed unit. Film magazines are for 200 ft or 400 ft loads. The DC motor is mounted downwards as a handgrip.
The camera projection matrix is derived from the intrinsic and extrinsic parameters of the camera, and is often represented by the series of transformations; e.g., a matrix of camera intrinsic parameters, a 3 × 3 rotation matrix, and a translation vector. The camera projection matrix can be used to associate points in a camera's image space ...
