Zooming
To zoom, turn the lens' zoom ring.
Be sure to finish zooming before focusing.
● ●
Zooming after focusing can affect the focus.
Blurring may temporarily occur if the zoom ring is
● ●
quickly rotated.
Zooming when the camera is OFF will result in
● ●
delayed focus.
Zooming during still image exposure will result in
● ●
delayed focus. This causes any streaks of light
that are captured during exposure to be blurred.

Hood (sold separately)
The EW-73C hood cuts out unwanted light and
protects the front of the lens from rain, snow,
and dust.
To attach the hood, align the hood's attachment
position mark with the red dot on the front of the
lens, then turn the hood as shown by the arrow
until the lens' red dot is aligned with the hood's
stop position mark.
The hood can be reverse-mounted on the lens
for storage.
If the hood is not attached properly, vignetting
● ●
(darkening of the perimeter of the picture) may
occur.
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.
