The E7 sports a full focus camera meaning beyond a certain point, everything is in focus. This means that taking photos is pretty much instant as you do away with the time taken to auto-focus. However, this does mean you cannot take macro/close up pictures/videos.
The E7 here is preproduction and was not really ready for video samples. So it’s probably not worth putting to much thought into this video. Also worth noting that the video is panning and would look better if the camera was set still. Finally this is shot indoors so cannot show the full potential of E7 video in optimum lighting.
