But EVERY "inch" chip is that way. 2/3 isn't 2/3 of an inch, and 1/2 isn't 1/2 of an inch, and 1/3 isn't 1/3 of an inch, and 1/4 isn't 1/4 of an inch.
They're all measured off the outside diameter of the old vidicon tube. None of them measures what their "inch" designation says.
But, they are all fairly consistent with each other. A 2/3" chip is 4x as big as a 1/3" chip. And a 4/3 chip is 4x as big as a 2/3" chip.
Ok thanks for explaining, I didn't know all this, now I do. So how much is the diameter of a 35mm chip then, in inch?
