In pro cameras, Sony, Alexa and some of the very high end ones, come with internal ND filters? What would be the reason? Just only ergonomics? I think ND filters inside the camera is more secure, more ergonomic and also because it is after the lens and before the sensor final image in sensor would be more accurate comparing to external ND filters.
What do you think?
Is internal ND filter should be in Axiom? Why? Or why not?
Where and how should be located?
How can it be modular hardware?
