Filter Mounting Thread - Canon EF 100-400mm f/4.5-5.6L IS USM Instruction

10. Hood
The ET-83C hood can keep unwanted light out
of the lens, and also protects the lens from rain,
snow, and dust. Fit the hood to the hood mount,
then turn it in the direction of the arrow to attach
it securely. 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.
11. Filters
(Sold Separately)
You can attach filters to the filter mounting
thread on the front of the lens.
●
Use a polarizing Canon filter (77mm).
●
To adjust the polarizing filter, first remove the
lens hood.
