X920 adds level gauge, Level Shot function and built-in WiFi. The high-end body also is capable of plug and copy HDD recording, has a 1,152k-dot touch-enabled 3.5-inch LCD, and a 25x optical zoom lens with tilt and blur correction. In other words, otherwise it is X900.

An 263,424-dot equivalent EVF is complete crap, as usual, it is not updated for last 7 years, I think.

The HC-V720 is lower in the lineup, offers exactly SAME 21 optical zoom lens as V700 (just added number in digital zoom) added built-in WiFi, 20.4-megapixel faked still picture capture, and an old 3-inch touchscreen LCD. The V720 also allows for plug and copy HDD recording and also adds near-field communication for easy control utilizing a smartphone. And yes, 1/2.33" sensor spec is used for marketing and active stabilizer with only small central portion used for actual image.
