Marketing lingo aside, there's MTF graphs at the bottom. And to me they are believable.
The 35/1.4 seems like it might have extremely subtle wavy distortion, some very minor curvature of field that goes away completely by 5.6 and very even sharpness across the entire frame by 5.6. So performance wise this seems to be on par with any other modern aspherical lens. I do like the automatic depth of field indicator, it's design seems creative, I wonder how well it would work in real world use.
The 28/1.4 MTF has a similar signature to the 35/1.4 but as expected for such a fast wide lens it does not improve as rapidly as the 35/1.4 when stopped down and the corners still lose a bit of definition by 5.6. Field curvature is however well controlled but some minor waviness remains. Distortion is harder to read for me in this graph, if I had to take a guess I would say it's also almost distortion free with a minor dip toward the outer extremes of the frame.
EDIT: From the meridional/sagittal lines it looks like the 35/1.4 has very smooth out of focus rendering, the 28 not as much but still not bad. No surprises there, really
Also I for one am glad these lenses exist and that the Chinese are making them. No one is forcing you to buy these things.
Imagine people griping like this in 1950 whenever a new Japanese lens maker entered the fray with some offerings. You'd have nothing to collect today! Sheesh.
