    So some numerical trick like the nm values of chip technology or the given size of harddiscs. Somehow expected something like that.
    I looked it up, according to wikipedia a 1" sensor is 13.2 x 8.8 mm² which would be 0.63" diagonally.
    Still impressive, but deception nonetheless…

      It’s so old it’s not really a deception to optics/film nerds (even digital camera nerds), it’s just a type more related to sharpness/use of the sensor.

      A lot of such measurements relate to the film norm being 35mm (like, the 200MP periscope lens & sensor in this phone has a 300nm focal length, the sensor being a 1/1.4" type sensor instead of the 1/1 like the main camera).

      The size is usually given per pixel 1.6 µm in this case (8120 x 6180) for the main sensor.
