Lens File stores the data to compensate the differences of the white shading, flare balance, white balance,
which occur when the lens extender is set to ON. It also stores the minimum f-stop value and name of the
lens. Lens File data of up to 16 files can be stored in the camera. The adjustment data can be called by
