Hood Mount; Zoom Ring - Canon EF 70-300mm f/4-5.6 IS USM Instruction

3. Hood (Sold separately)
The ET-65B hood can keep unwanted light out of
the lens, and also protects the front of the lens
from rain, snow, and dust.
Attach and align the hood to the hood mount on
the front of the lens, and turn the hood as shown
by the arrow to secure it.
The hood can be reverse-mounted on the lens
for storage.
¡The front end of the lens rotates, so hold it when
attaching the hood.
¡Part of the picture may be blocked if the hood is
not attached properly.
¡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.
4. Zooming
To zoom, turn the lens' zoom ring.
Be sure to finish zooming before focusing.
Changing the zoom ring after focusing can affect
the focus.
