This is an interesting one. It’s definitely for shooting a single particular type of thing, but it looks like it does the job quite well. It’s the SmallRig x Mikevisuals Tracking POV Kit (buy here), and it’s designed for sticking objects in front of your camera.
But not in the filter kind of way. This makes whatever you stick in front of the camera your main subject, with the world whizzing by in the background. Of course, there is some post-work required to remove the rig.
