In my experience, this depends on the area of application. For photos in nature or the city, the kit lens was sufficient for me in terms of focal length. In the zoo, however, I would have liked to be able to zoom in a bit closer to the animals. Over a 1 month trip, the kit lens was sufficient for about 90% of the pictures. Next I will definitely buy a lens with a longer focal length range. However, I am only a layman without any special use cases. I can't give a verdict on the quality, but it was enough for me.
