They came up with something that is called the “value angle” when talking about the various lens mounts out there for photography.
What is the value angle?
The formula for value angle = 2 × arctan ((mount diameter – sensor diagonal) / (2 × flange distance))
Which in layman’s terms, is a calculation that takes into account the flange distance of a mount. the size of the mount itself against the size of the image sensor.
In Fujifilm’s mind, this formula tells us and them how difficult it is to design top performing lenses for a particular mount. The winner? The EF-M mount from Canon. The latest RF mount from Canon didn’t do as well according to the formula.
