I can now see why photojournalists would often keep a very wide angle zoom on one body all the time. It can capture a huge scene but is also useful in crowded environments in getting close to a subject and showing their surroundings to give context. Its challenging to use because of perspective distortion at the edges of the frame. But it can give spectacular results.
This isn't the sharpest example because light levels were falling and I was shooting at 1/15 sec.
Still pretty decent

For those keeping score we're now up to 6 lenses...
