Product placement
FUJINON XF400mmF4.5 R LM OIS WR: (a) ACTS — it is shown being attached to a camera, operated by a photographer in the field, and its specific technical capabilities (portability, focal length, stabilization) are highlighted as the primary subject of the video. Removing it would remove the entire purpose of the video. FUJIFILM: (a) ACTS — the camera body is operated and the brand logo appears as the manufacturer of the lens and camera system. Removing it would change the identity of the product being showcased.
