Shooting a group of people in a tight space is a good time to pull out the ultra-wide angle lens. Ultra-wide angle focal lengths are not going to be the most-pleasing option from a perspective standpoint (notice how large that left-most foot looks?), but sometimes getting everyone in the shot is more important.
