Also, the link is for the Canon/Nikon model
The one for Pentax has 'Neewer' on it as the brand?
You need a dedicated flash for HSS, the Yongnuo YN560 is a non-dedicated flash, which is universal, it will work on anything with a standard hotshoe or sync port. Because of this, it doesn't matter what the listing says, the YN560 works the same on all brands, they only really make one model. The stores list brand names to draw in users of those brands.
Yongnuo does sell some dedicated flashes with all of the TTL features for Canon and Nikon, but not Pentax, that would be the YN467, YN468 and YN565.
