No, it's all very complicated this sensor size lark. The quoted dimensions are historically based on TV camera tube sizes, and the sensor itself is typically about two-thirds that size - no wonder they continue to use a more flattering measure than reality.

what happened the blue door???
It might just be my opinion or it could have been the poor autumn light, but those test shots looked a bit under-saturated and cold to me.
The CX2 might not be optimal for consumer slow motion video, but 120fps sounds like it could be an option if you were so inclined.
I was dubious...
about the miniature mode, but I quite like the look of that!
BTW, I hope Mr Cole has reported himself to the relevant authorities for the suspicious activity of recording traffic AND a CCTV camera in the video!
