Richard Wong tested the new 7.5mm f/2 lens:

There are a lot of things to like about the Laowa Compact Dreamer 7.5mm f/2 lens. The overall image quality is excellent. The superb sharpness and virtually lack of colour fringing can easily make you forget about the less than perfect flare and vignetting performance. The lack of auto stop down aperture isn’t really an issue for mirrorless cameras and manual focus shouldn’t really be a problem either for an ultra wide angle lens as well. Build quality is great, the lens feels very solid and well made when you hold it in your hand. The best thing about this lens is that it’s so small and light, you should be happy to just leave it in your camera bag all the time even when you are not planning to use it. No matter you are a photographer or videographer, you should really check out this lens.

Of course I hope you are aware all this will be done at your own risk.
