Sony ILCA-77M2 - Manual (Page 39)

Note
Attach the lens hood properly. Otherwise, the lens hood may not have any effect or may be partially
reflected in the image.
When the lens hood is attached properly, the lens hood index (red line) matches the red index mark
on the hood.
Remove the lens hood when using the flash. Otherwise, the lens hood blocks the flash light and may
appear as a shadow on the image.
To store the lens hood after shooting, attach the lens hood to the lens backward.

Notes on changing the lens
When changing the lens, if dust or debris gets inside the camera and adheres to the surface of the
image sensor (the part that converts the light to an electric signal), it may appear as dark spots on the
image, depending on the shooting environment.
This camera is equipped with an anti-dust function that causes the image sensor to vibrate a little when
the power is turned off to prevent dust from attaching to the image sensor. However, always make sure
to attach/remove the lens quickly away from dusty locations.
