Lens count doesn't include 3rd party products. Typically, camera bodies with shorter flange focal distance can be adapted more readily to lenses with longer flange focal distance.Д¬an use any of the 24x36 mm lenses and the FTZ mount adaptor. If the difference is small, other factors such as the sizes and positions of the mounting flanges will influence whether a lens can be adapted without optics. A lens with a longer FFD can be more readily adapted to a larger number of camera bodies (those with a shorter FFD). A camera body with a shorter FFD can accept a larger number of lenses (those with a longer FFD) by using a simple adapter. A simple non-optical adapter holds the longer FFD lens the appropriate additional distance away from the sensor or film on the shorter FFD camera. Optics to correct for distance introduce more cost and can lower image quality, so non-optical lens adapters are preferred. FFD determines whether infinity focus can be accomplished with a simple non-optical adapter. Lenses can be adapted from one mount (and respective FFD) to another. The range of this distance, which will render an image clearly in focus within all focal lengths, is usually measured to a precision of hundredths of millimetres, and is not to be confused with depth of field.

This value is different for different camera systems. Diagram illustrating the flange focal length of an SLRвЂ“type and a mirrorlessвЂ“type cameraДЇor 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), or register, depending on the usage and source) of a lens mount system is the distance from the mounting flange (the interlocking metal rings on the camera and the rear of the lens) to the film or image sensor plane.
