Overall, the C922 is a brilliant camera and maintains the strong position in the market that the C920 holds, and while I dont think the C920 is going anywhere anytime soon, I do think the C922 is the better option for content creators. For anyone looking for a new camera, the C922 offers excellent value, and the 720p/60 video quality makes it the superior choice over the C920, or indeed many of its competitors.
