Tech@ZWO Sorry, to disagree … again.
It is one thing to call it a 1” format sensor (which is kind of correct for whatever historical reasons), but a completely different and wrong thing to claim in the drawing the actual dimension is 25.4 mm (= one inch) in the diagonal.
Especially, when in your table you are writing that the diagonal is only 16mm. So your drawing is completely wrong, you claim a different size than in the spec sheet and on top of it, you are not only fully aware of it, but also you do not seem to have a problem with it, either.
Searching the Sony website, I could not find any reference to a 25.4 mm diagonal for the 1” format chip.
