Camera changes scale bug?

After my discussion with Thomas I think that the way the camera is staying constant when you change units is not correct.
I used a 50mm lens and put it 20mm away from my focused object which is a 1mm high cone, then I changed units to kilometers, my lens is now 20km from my,now, 1km high cone, i have not changed the 50mm but the scene also didn't change, I don't have to reajust anything and this is not normal if the camera is supposed to have a real world reaction.
To have exactly the same size in my view finder I should use at least a 1000mm lens to focus on an object 20km away, or am I missing something :?:

Are you are setting up yourself for an optical illusion ?

An object twice as big which is twice as far looks the same on the viewfinder.
