Re: G12 Sensor Size

And if you then take your calculator and believe that the sensor size (diagonally) is 1/1.7" = 14.9 mm, you'd be mistaken. Sensor sizes are described in a format inherited from video tubes and 1/1.7" is the diameter of glass tube inside which the sensor would fit.

The actual sensor size is 7.44 by 5.58 mm or 9.3 mm diagonally.
