Attaching the Lens Hood

It is recommended that you use a lens hood to reduce flare and ensure maximum image quality.

Align the red line on the lens hood with the red line on the lens (lens hood index), then insert the lens hood into the lens mount and rotate it clockwise until it clicks into place and the red dot on the lens hood is aligned with the red line on the lens (1).

Zooming

Rotate the zooming ring to the desired focal length.

About the zoom smoothness switch (See illustration )
You can set the tension for rotating the zooming ring with the zoom smoothness switch.
To decrease the tension, slide the zoom smoothness switch to "SMOOTH." To increase the tension, slide the zoom smoothness switch to "TIGHT."
To keep the tension for rotating the zooming ring light, it is recommended that the zoom smoothness switch be set to "SMOOTH."
To prevent unintended movement of the lens end while shooting at an upward/downward angle or carrying around the lens, it is recommended that the zoom smoothness switch be set to "TIGHT."

Adjusting the Aperture

IRIS LOCK switch

• Lock: You can lock the aperture ring at "A" on the aperture scale, or rotate it between f/2.8 and f/22.
• Release: You can rotate the aperture ring between "A" and f/2.8 on the aperture scale.

When you align "A" on the aperture scale to the aperture index, the camera is set to auto iris mode and the exposure is set by the camera. And you can adjust the amount of light manually between f/2.8 and f/22 by rotating the aperture ring.

Notes
Set the aperture click switch to "OFF" when shooting movies. (See illustration )
When the aperture click switch is set to "OFF," the sound of the aperture ring is reduced. (For movie recording)
If you change the aperture value while shooting a movie with the aperture click switch set to "ON," the sound of the aperture ring will be recorded.
