Perhaps this is where the confusion comes in...

1/3" is a camera sensor size but it's not related to any dimension of the sensor!

Sorry, that just popped right out at me.

And "well-popped" it is.

I was not looking for mathematical accuracy - the salient point being that, in round figures, the "breaking point" is around 3mm, 1/3" depending on which physicist one consults - there was quite a "dust-up" some time ago between followers of two different [real: Ph.D] Physicists on another forum.

Thanks for your input.
