I think its Set on Wide not narrow as when im stood up to the stumps you get more in.
Not yet tried it on narrow for cricket.
The quality is better at 4k obv but only get about an hour of recording
I find 1080 fine. I played around with mine yesterday and 'Narrow' view isn't an option on 2.7 or 4k so I think you'll find you have to use 1080 or less.
I would 110% recommend using the mobile phone App to run it. Very, very easy to use. Allows you to adjust all the settings on the fly like Protune, low light, view your field of view as its recording which is great because then you can tell straight away whether you have your recording angle/positioning correct, rec/pause, delete files easily and many more options.
