My K3 has no problems with 35/1.4 Art and 18-35/1.8 Art lenses focusing.

In fact K5 and K3 both struggle significantly to nail focus with FA35/2 and especially FA50/1.4 which are Pentax own lenses, but the hit ratio is random. No matter how you calibrate. K3 being a tiny bit better than K5.

Maybe you have exceptionally good copies from Sigma and particularly bad copies from Pentax ?

Owning both FA 50 and the Sigma 18-35, I notice the complete opposite of what you say. I used the FA 50 on K100D, K70 and K3III (and the Sigma not on K100D of course).
