No sense

Focal length is a physical characteristic of the lens as well aperture, its mass and volume.

Of course a 50 mm lens will have different angle of view if used on a Nikon System 1, DX or FX - as well if mounted on a larger format film camera.

Aperture is the same. I read some people insisting to refer a f/1.2 lens as a f/3.3 lens only because it is used on Nikon System 1. What non-sense! f/1.2 is a physical property of the lens, it has no relationship with the fact you will attach it on a specific camera or to use it as a paper weight.

The same for the mass and volume: if the lens is 233 g of mass, it will be independent of the application you give to it.

Do you think it will have sense to create a scale with "small inches" where each "new" inch corresponds to just 1/4 from the "old" ones only because I would use it to measure small things? Absolutely!
