Diagram illustrating the flange focal length of an SLR–type and a mirrorless–type camera. For an interchangeable lens camera, the flange focal distance (FFD) (also known as the flange-to-film distance, flange focal depth, flange back distance (FBD), flange focal length (FFL), back focus [1] or register, depending on the usage and source) of a lens mount system is the distance from the ...

The Micro Four Thirds system (MFT) of still and video cameras and lenses was released by Olympus and Panasonic in 2008; lenses built for MFT use a flange focal distance of 19.25 mm, covering an image sensor with dimensions 17.3 × 13.0 mm (21.6 mm diagonal).
The Pentax Q series is a series of mirrorless interchangeable-lens cameras made by Pentax and introduced in 2011 with the initial model Pentax Q. [1] As of September 2012, it was the world's smallest, lightest interchangeable lens digital camera. [2] The first models used a 1/2.3" (6.17 x 4.55 mm) back-illuminated sensor CMOS image sensor.
The flange distance is 105mm. The RZ67 name is adopted from the model name of the Mamiya RB67 (in which RB stands for "Revolving Back"), which was first introduced in 1970. The main difference between RB67 and RZ67 is that the RB67 is completely mechanical. The RZ67 body is able to transmit exposure information from the lens to the body.
Nikon Z-mount (stylised as ) is an interchangeable lens mount developed by Nikon for its mirrorless digital cameras. In late 2018, Nikon released two cameras that use this mount, the full-frame Nikon Z7 and Nikon Z6. In late 2019 Nikon announced their first Z-mount camera with an APS-C sensor, the Nikon Z50.
M42 thread mount cameras first became well known under the Praktica brand, and thus the M42 mount is known as the Praktica thread mount. [1] Since there were no proprietary elements to the M42 mount, many other manufacturers used it; this has led to it being called the Universal thread mount or Universal screw mount by many.
The camera's small sensor size (1/2.3 inches) means that the Q has a crop factor of 5.6× (compared to full-frame 35mm cameras), as well as a short flange focal distance (FFD). With the 5.6× crop factor, a 100mm macro lens (for example) results in a 35mm equivalent field of view (FOV) of a 560mm telephoto.
