Attaching and Detaching a Lens
34
A lens hood can block unwanted light and diminish rain, snow, dust etc.
adhering to the front of the lens. Before storing the lens in a bag, etc.,
you can attach the hood in reverse.
If there is no index mark on the lens and hood:
Attach the lens hood.
Turn the hood as shown by the arrow
to attach it securely.
If there is an index mark on the lens and hood:
1 Align the red dots on the hood
and lens edges, then turn the
hood as shown by the arrow.
2 Turn the hood as shown in the
illustration.
Turn the hood clockwise until it
attaches securely.
Attaching a Lens Hood
If you do not attach the hood properly, it 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.
When using the camera’s built-in flash, detach the hood. Otherwise, the
hood will obstruct part of the flash.
