the fisheye effect does distort the perspective quite a bit. Jeff’s vid looks a bit too much like a video game than a real life vid.
I think this camera's software reduced the fisheye effect the most that I have seen.
The videos look like from a videogame because this is exactly what they do in video games -- use the rider's upper body as the frame of reference!
The only better POV moto racing footage that I have seen was from a racing drone following a rider, posted somewhere else in this forum. it does look like real-life, except drones following riders is not the real life yet, LOL!
