Depends on who you are and what you want to achieve. If you're a beginner and/or don't have access to professional gear, it's great to have a way of shooting "the professional way" on whatever you happen to have around. You get most of the manual control a proper camera gives you with an interface very similar to that of a Blackmagic camera, so when you finally find yourself in front of a real one, you already have some experience with it.

And while the image quality definitely doesn't compare to that of cinema cameras, 90 % of the time, it doesn't have to.
