7. Hood
The ET-74 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.
•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.
You can attach filters to the filter mounting thread
on the front of the lens.
8. Filters (Sold Separately)
If you need a polarizing filter, use the Canon
Circular Polarizing Filter (67mm).
•To adjust the polarizing filter, first remove the
lens hood.
