This is a classic lens flare sweep, using a standard glass lens. As with a lot of my light leaks, they work better when sped up, but I present them at the original slow speed to give you the most options. The clip ends with a nice rainbow pattern that I captured as a bit of a bonus.
You can download it in 1080p HD, in Quicktime ProRes format from here:

If you are super kind and get something out of using these then please donate a small amount and I can do some more -
