Hood (Sold Separately)
The ET-60 hood can keep unwanted light out of
the lens, and also protects the lens from rain,
snow, and dust.
Turn the hood in the direction of the arrow to
attach it securely.
The hood can be reverse-mounted on the lens
for storage.
¡When attaching or detaching the hood, grasp
the base of the hood to turn it. To prevent
deformation, do not grasp the rim of the hood to
turn it.
¡Part of the picture may be blocked if the hood is
not attached properly.
