This manual on page 101 states that the camera has a sensor size of 6.3mm (1/2.9 type) I found this on sensor sizes ant tough that I could aply the 1" 16mm rule to this sensor.
1" = 16mm 1/2.9" = 5.517241379
1/2.9" * 25.4 = 8.75862069
But both methods don't give me 6.3mm What am I doing wrong and how would I get from the 6.3mm diagonal to the horizontal and vertical size.
Some more details are described in this post.
