Note on changing the lens
When changing the lens, if dust or debris gets inside the camera and lands
on the surface of the image sensor (the part that acts as the film), it may
appear on the image, depending on the shooting environment.
The camera is equipped with an anti-dust function to prevent dust from
landing on the image sensor. However, quickly change the lens away from
dusty locations when attaching/removing a lens.
If dust or debris lands on the image sensor
Clean the image sensor using [Cleaning Mode] in the
(page 36).
