The interior shots, especially small hotel rooms would certainly have become better with a wide-angle lens.
But I no longer use the Ulanzi OP-05 wide-angle lens because the picture quality is not so good.
In the future I will use my new iPhone 11 Pro Max mounted on Osmo Mobile. The ultra wide angle is similar to that of my YI4k Plus. However, the picture quality of the new iPhone is even better.
For video you are stuck with the field of view you are getting.
A downside of wide angled lenses is that they usually distort the image.
And it is not (always) the best field of view for certain shots.
I can highly recommend the new Freewell wide angle lens. Runs rings around the Ulanzi in terms of image quality. Not sure about the availability, as I know they were so popular the manufacturers were having a job keeping up with demand. Hopefully sorted now though.
