You can find information on using the lens in “ Operating Instructions.”

Attaching/detaching the lens
To attach the lens
1 Remove the front and rear lens caps and the camera body cap.
2 Align the orange index on the lens barrel with the orange index
on the camera (mounting index), then insert the lens into the
camera mount and rotate it clockwise until it locks.
Do not press the lens release button on the camera when mounting the lens.
Do not mount the lens at an angle.
To remove the lens
While pressing and holding the lens release button on the camera,
rotate the lens counterclockwise until it stops, then detach the lens.
Attaching the lens hood
It is recommended that you use a lens hood to reduce flare and ensure
maximum image quality.
Loosen the locking screw on the lens hood and slip the lens hood
over the front of the lens. Check that lens hood is attached properly,
and then tighten the screw.
When using a built-in camera flash, make sure to remove the lens hood to avoid
blockage of the flash light.
Attaching the lens front cap
When storing, turn the lens hood back over the lens, and tighten the screw to
secure the lens hood to the lens.
Attach the lens to the lens front cap firmly, zip the fastener tape and tighten
with the stopper.
When attaching the lens front cap to the lens hood, align the holder of the lens
hood on the hole of the lens front cap.
Attaching a tripod
Attach the tripod to the lens, not to the camera.
To change vertical/horizontal position
Loosen the collar-locking knob on the tripod-mounting collar (1) and rotate
the camera either direction. The camera can be quickly switched between
vertical and horizontal positions while maintaining stability when using a
tripod.
Gray indexes (collar indexes) are located at 90° intervals on the tripod-mounting
collar. Align a gray index on the tripod-mounting collar with the gray index
(lens index) on the lens to adjust the camera position precisely (2).
Tighten the collar-locking knob firmly after the camera position is set.
