Sensor Sizes and their Calculations?
I am confused.
If the Sony RX100 has a sensor size of 13.2 x 8.8 mm, then how does it have a 1" sensor?
Using Pythagoras Theorem, I can't see how the Sony RX100 could have a diagonal length of 1"/25.4 mm???
Likewise, how is a Canon G1X at 18.7 x 14 mm, classified as a 1.5" sensor?
