Nokia Lumia 900 Video Quality

I went to the Queens Zoo with my Wife & son to enjoy the great weather here in NYC, but also to finally test out the Camera as well as Video on my Lumia 900, now i have read a lot of reviews concerning the camera quality on the Lumia 900 & to be honest a lot are disappointed. I haven’t seen much on the Video Front, below i have taken 3 quick videos & i have to say I am pretty impressed with the Quality, from the sound to the continuous auto focus, i didn’t have to tap screen or initiate focus in anyway just turned on video and started to record.
I know the Lumia records in 720p while other devices are using 1080p, I am not concerned about the specs more so the quality.
Please let me know your thoughts as I am no professional.
