4K60 Narrow FOV??!!!

When in 4K60 the image is recorded pixel-to-pixel from the center of the sensor instead of being downscaled from the full area of the 5.2K sensor. This obviously changes the FOV and results in a 2.7x magnification factor (instead of the usual 2.0x MFT mag factor).

So what's the trade off resolution wise? I was excited about the 4K 60 but I'm not sure I like what I'm seeing in the H264 version.
 
Well, the resolution recorded is 3840x2160, so it's full 4K, but no, it's not the full 5.2K of the sensor. However, you're able to record at 60 fps, so there's that!
 
I suspect, however, that, like the Phantom 4 Pro, the x4s doesn't do true 4k in 60fps mode -- it's most likely line skipping in order to read out the sensor that fast.
