I use this exclusively for recording 360 virtual tours and Google Business View tours. I like the lens: the images are sharp, the colors are good, but the price is too high! I have a Rokinon 8mm lens with roughly the same coverage. It says "Fisheye" on it, but it's actually not, which allows me to use it for apps other than VR Panos. It's also 1/3 the cost of a Sigma 8mm and works great. The only reason I (reluctantly) bought the Sigma 8mm is because Google needed it. Save money and get Rokinon 8mm.
