It’s not a MTF camera but certainly one very cool action camera from Olympus! On top you can watch the video review by Digitalrev. And on that CameraLabs article you can read the full action camera review:
On the whole the TG-Tracker tells you more about the environment you’re using it in than any other action camera I can think of. Whether you actually need it all and how useful it is is another question. The GPS worked faultlessly (even on the London underground, which was pretty impressive) and I like that you can log when you’re not taking pictures at the flick of a switch. The other sensor data – direction, altitude, temperature and vertical distance travelled is novel and very accessible from the camera. It’s fun to have, but probably not all crucial for most people.
