Record data for non-CPU lenses attached using an optional
mount adapter. Recording the focal length and maximum
aperture of non-CPU lenses allows them to be used with some
camera features normally reserved for CPU lenses, such as on-
board vibration reduction.
Dirt or dust entering the camera when lenses are exchanged or
the body cap is removed may adhere to the image sensor and
affect your photographs. The “clean image sensor” option
vibrates the sensor to remove dust.
