Attaching a Lens Hood
A lens hood can block unwanted light and protect the front of the lens
from rain, snow, dust, etc. Before storing the lens in a bag, etc., you can
attach the hood in reverse.
If the Lens Hood and Lens Have a Mount Index
If Neither the Lens Hood Nor the Lens Have a Mount Index

may obstruct the image's periphery, making it look dark.
When attaching or detaching the hood, grasp the base of the hood when
turning it. Grasping the hood's edges when turning it may deform the
hood, resulting in failure to turn.
