Lens File
The Lens File stores the differential data from the Reference File.
The lens file is stored white shading generated when the extender is turned on, flare balance, white balance, F value at
the lens open end, lens name, and other data. These adjustment data are stored in the camera.
Lens File data of up to 16 files can be stored for a lens that is not compatible with serial communication.
The adjustment data can be called by selecting a Lens File.
Note
Before creating the Lens File, perform the necessary adjustments by using the lens usually used and register the Reference
File.
