Sorry Rover, I couldn't resist:
"due to the expensive use of aspherical elements"
Permission granted.
I still have one more left for myself anyway:
“EXIF data is not provided so mechanisms such as image auto-correction.” - on the bottom of the first page.
The second part is either missing the predicate, or should have "to" instead of "so" (I think the first one is more likely).
Anyway, the lens: the tinfoil hatter in me, having read the revelation that the new Tokina 85/1.8 is the same optically as the Viltrox unit Klaus had just tested, starts to think of a possible hidden relationship between this one and the Tokina Firin.
Of course it might be nothing, but... 
Other than that: it looks like the f/1.8 aperture is mostly "special purpose" but pretty good all over at f/2.8, more than can be said of the old Sigma with the same stats (which was notorious).
