We found the 50 Dollar Follow Focus on Kickstarter.com. It was invented by a guy named Wiley Davis. He likes to write, shoot video, and make things out of metal. This is what drove him to create an awesome looking follow focus for an excellent price. Wiley is trying to get funding to produce it more efficiently. Check out the video above for more info.
