K-01 and older lenses

I downloaded the K-01 User Guide with a view to figuring out which of my older lenses I could use with it. I remain somewhat in the dark.

Late 1990s F1.4 50mm, with screw-autofocus. Does the K-01 have screw autofocus capability, or am I limited to manual focus with that lens?

1970s F3.5 135mm manual (no A-setting on the aperture ring). If I use that lens, is there an easy way to set the camera to expose properly?

Part of the attraction of the K-01 would be to use older lenses, but that advantage would be severely diluted if in practice it turned out to be a pain.

Thanks,
