k-70 and Sigma 18-35 1.8

Hi,

I'm thinking about sigma 18-35 for my k70 but I know that this lens may have some issues with AF.

I've found many different opinions, some of them say that AF works well but others that are almost unuseful with big apertures. Reported issues caused that their problem is in inconsistency, making 10 images one by one cause that some of them are back focused and other front focused so the problem cannot be fixed by the sigma dock.

I think that a huge amount of positive reviews come from K5II users and negative from K3, K3II that start me thinking that maybe this lens works just better with SAFOX X rather than XI.

K70 has SAFOX X which suggests that should be fine but it's just my consideration. It will be good to hear the opinions of people that use such of set
