Great stuff!.. However, I should point out that the Laowa 12mm lens mentioned in the intro isn't f/2, just f/2.8. 
If you need an example to replace it, there's the Samyang 14mm f/2.4 XP (or whatever it's called). Both this and the Irix are only 1/2 stop (in practice probably even 1/3, because the camera would probably round that aperture down to f/2.5?) brighter than the "norm" though, not 1 1/3 stop, so I'm not sure they really count at all. This SIGMA is totally unique.
