Fuji invents new scale to value the different mounts

At the Fujifilm X summit Fujifilm introduced the new term “Value Angle” to value the different mounts. In short: The Greater the value angle, the more precise and easier a lens can send light to the sensor. A wider value angle gives more flexibility for lens design and allows for more light and less digital correction.

It will surprise no one that Sony FE ends up last:
