1. The coverage is not big enough, so if you plan to shoot indoors (close space), you will leave something to be desired and you will be disappointed.2. Autofocus is unstable at night, focuses for a long time when there is a bright light in the foreground; Because it doesn't have manual focus, some night shots are blurry.3. Software. The bundled software to convert videos to Blu-ray DVD is very slow (not only the burning part, it depends on your DVD burner), and it's difficult to merge/merge videos with the bundled software.
