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.

DxOmark tested the new Sigma 30mmf /1.4 MFT lens. And as you can see from the score below the lens is as good as the Panasonic-Leica 25mm lens:

Boasting a fast maximum aperture and short minimum focus distance, the Sigma 30mm f/1.4 DN is a good standard prime option for MFT shooters. Sigma’s precision engineering ensures the good transmission, distortion, vignetting, and chromatic aberration results you’d expect from a prime. Sharpness isn’t outstanding, but it’s on par for a lens of this type, with the best results achieved at f/2.8 and f/4. The own-brand Panasonic 25mm f/1.4 does offer slighter greater and more uniform resolution at mid-aperture settings, but it distorts more than the Sigma, and fringes a little more in the very far corners, too. What’s more, it costs almost twice as much as the Sigma 30mm f/1.4 DN, making Sigma’s third-party alternative the better value-for-money option.

You can buy the Sigma on thos elinks at Amazon, BHphoto, Adorama, WexUK, Jessops and Calumet Germany.
