Photographic brand placement in Ghost In The Shell
The 1990's/2000's anime series "Ghost in the Shell" (3 movies, 2+ TV seasons) is about a specialized secret police counterterrorism unit operating in a futuristic Japan in the 2040's, with many of the characters having cyborg body parts, etc.
In several different scenes across different episodes, current optics/camera brands can be seen on devices used by the characters, such as a tiny "Carl Zeiss" on the iris of the main character's cyborg eyes, and a separate scene where a character uses a set of binoculars labeled "Mamiya".
Just thought this was interesting, later I can add links to screenshots.
