Less is more. Keep it still and no zooming. Sometimes that's all that's necessary to be a great photographer. Nice sharp picture though, not many 4K resolution out there of this.
Thanks for the advice. I know all this, but I was not in a very comfortable position without a tripod. I came running only to check how well the zoom works on the Iphone’s camera, but unfortunately not good enough. So I agree better not to use Zoom at all)
