Normally I’m not much of a fan of the warped perspective of ultra-wide angle lenses but there are a few instances where they come in handy. I usually carry a fixed 20mm lens in my bag for those occasions. One of my favorite things is constructing photos with multiple layers of action in the frame and on a packed dance floor that 20mm lens is the perfect tool for the job. It’s small and unobtrusive and allows me to get right in the middle of the action. When everything lines up right you get wonderfully dynamic photos like this that really capture the feel of being there.
