Entapano posted a series of video he shot with the new Entaniya Fisheye 250 E lens. You can find those video here: youtube.com/channel/UCYfIedMS6Im1E-ePO0SplGQ/videos. Keep in mind that once you play the video you have to drag and drop with your mouse cursor to move around.
Now if you want that lens things are a tiny bit complicated: You have to buy the MFT mount lens (here on Adorama) and then buy the official Entaniya Sony E mount Adaptor for MFT 250 Lenses (again here at Adorama).
The official lens site can be found at entapano.com/en/fisheyelens/microfourthirds_fisheyelens.html
