Entaniya announced the Entaniya 250, a 250-degree fisheye lens for Micro Four Thirds sensors that may provide very high image quality for a hemispherical 360 camera.
360-degree cameras often use sensors that are 1/2.3-inch or 1/3.2-inch. The Indiecam Naked Eye, with a 2/3-inch sensor is already considered a large sensor (and indeed it is, relative to a 1/2.3 inch sensor). However, Entaniya’s lens is for a Micro Four Thirds sensor, which is gigantic even when compared to the Naked Eye sensor:

If you look at the diagram, you can see that a Four Thirds sensor dwarfs even a 2/3-inch sensor. (Note: Micro Four Thirds has the same size has a Four Thirds sensor). Whereas the surface area of a 1/2.5 inch sensor is 25 mm² and a 2/3 inch sensor has 58.1 mm², an MFT sensor has 225 mm².
There are three variants of the Entaniya 250 for MFT. The 3.0mm variant can fit a 250-degree circular fisheye image within the MFT sensor, thus making it possible to capture hemispherical 360 photos and videos.
