Nikon NIKKOR Z 24-120mm f/4 S Lens (Z) - Manual (Page 21)

Using the Lens on Cameras with a Built-in
Flash
Shadows will be visible in photos where light from the built-in flash is obscured by
the lens or lens hood. Remove the lens hood before shooting. Note, however, that
depending on the distance to the subject, and in the case of zoom lenses also on
the lens focal length, shadows may appear even when the lens hood is removed.
• For the information on focal lengths and subject distances at which shadows
will not appear in photos taken with a built-in flash, visit the site below.
