Thanks. The only thing I worry about with shooting in 4:3 is that I always output videos in 16:9, and that composing for 16:9 might be difficult if the camera LCD is showing a 4:3 aspect ratio
If you use it for pov on helmet on in general, shooting in 4:3 ratio makes it easier in post to get the right angle you need for your video. But I understand if you are using it for vlogging or general video, then you always need to consider what will be show or not in 16:9 ratio.
