For anyone interested on how the Laowa 12mm f/2,8 ZERO-D performs + the Laowa Magic shift converter (1.4x converter + shift mechanism).
Sony A7 II, ISO100, 1/50, f/8 (I believe):

No corrections applied (distortion or CA). Standard unsharp mask in ACR (40). For me the result is great, bearing in mind we are adding optics in front of a 12mm to make it a shiftable 17mm.
