I obtained one of the first H's available and have not regretted it for a second. Is the camera perfect? Probably not but using the photos below you can tell me if it's good or bad. One is the original JPG and the second is the same JPG after some light work. Look at them on a 32"-40" screen with 1080 or better resolution. Natural setting, lighting set to sunset/sunrise, no filters, camera set to 4k, 24fps. Still shot with a 14-17mph wind blowing.
I read about problems with every make and model multirotor there is on various forums, leading me to believe people prefer complaining over praising. A fair number of people complaining turn out to be the cause of their problems because they lack the knowledge and experience needed to fully comprehend how to use what they have, or elect to "cowboy" their equipment in ways contrary to what little is provided for general operating instructions with any of the models out there. I have little sympathy for people that modify antennas and other factory equipment and/or fly well beyond the distance people can see the aircraft to effectively control it, or have failed to learn anything about GPS and their flight control systems, who come back complaining about loss of control, fly away, or video drop out issues. Might as well blame a compass for pointing north. Others have some real issues but they are not as many as it might appear. Then you have the group that is part of the cheer leading team for any given manufacturer, but one in particular, that go to great lengths to disparage any equipment that may compete with their chosen manufacturer's sales volume.
So I don't regret anything about my H purchase. It has worked like it was advertised to. Camera focus is no big deal for anyone that really cares about it. Mickeyboo posted a real nice video showing people how to adjust it. It's not hard. All you need is an HDMI cable and a large screen to watch the results of your adjustment efforts. This one is the way it came out of the box.
