When the Japanese website Digicame-info spotted an upcoming announcement about the Olympus TG-Tracker, we didn’t know what to expect. I speculated that it could be a 360-degree camera. Well, info about the TG-Tracker has leaked to DigiCame-Info, and it does not seem to be a 360-degree camera. Here is the Google translation.
The specs show that the lens is a fisheye lens, with 204 degree field of view (the “lens” on top is actually a video light). However, it is not clear whether it is a circular fisheye or a rectilinear fisheye. If it is a circular fisheye then technically it could qualify as a hemispherical 360-degree camera, such as the Kodak SP360 4k, or the 360fly. If it is a rectilinear fisheye, then it can’t easily be converted to equirectangular view, which means that for all practical purposes, it would not be a 360-degree camera.
Edit: based on the lens hood, it is a rectilinear fisheye.
