Information about two of the newest cameras:
Runcam 3 first look. It looks like a good budget option, but it's disappointing to see it's only capable of 1080p and no superview.
Foxeer Box 4k Cam looks like a much better option, but the price is currently unknown. It supports superview, is waterproof and has a range of video modes including 4k and 1080p at 120fps.
