There has been some discussion about the lens on the H being a bit to wide for some peoples taste. One work around would be to shoot everything in 4K, then in post zoom into the footage to get the desired field of view. Thing is,I think you would be limited to the max frame rate in 4K and not being able to shoot @ 60 or 120FPS.
The other option is a straight swap out of the CGO3+ stock lens with a lens of a narrower focal length. Say 4.35 or 5.4MM. I have done this on GoPros and it afforded me the field of view I wanted. As just about ever manufacturer of these 1/2.5 CMOS sensor sized cameras use readily available M12 mount lenses,I see no reason that Yuneec has not done the same.
It appears that in order to gain access to the CGO3+ stock lens you need to remove the cameras shell via 8 screws which will reveal the lens,sensor board and antenna.It looks to me to be a pretty straight forward process. My only concern being what type of glue Yuneec used to hold the lens in place once they screwed it in and focused it at the factory.
