That is an exposed aspherical element, they all look like that as do fisheyes. Wide angles usually have the largest front elements. The exception is large aperture long telephotos.

There are lots of places where the subject is very close or very wide and the widest wide angle never seems like enough. This can include indoor shots to city streets.
