Just how easy is manual focus going to be on a K-1 though?
Got mine today. Manual focus is not too bad at all! The viewfinder is great! The images this zeiss are producing are spectacular!!

No experience with the Sigma ART 35MM but really do love my FA 31 Limited. Even if Pentax updates the 31 with quick shift, WR, and silent AF, I won't be replacing my copy. Its IQ is so good and consistent plus the build and operation of it just feels right. Definitely my favorite lens. It's a lifetime keeper, for sure.

This gentleman on Flickr has some 35mm Art shots. The anticipation for my K-1 is killing me!

The Sigma is sharper, but the Bokeh is not nearly as good as the 31mm IMO. I'm sticking with my 31mm until Pentax releases a D-FA* 35mm F/1.4.
Agreed. I own both lenses and the FA31 has microcontrast to die for and a much better BOKEH than the Sigma 35. The Sigma reduces specular highlights to circles and the bokeh can be very nervous. I use the Sigma on my D810 though and it is a stellar performer, resolution wise.

OTOH the Sigma 50/1.4 'art' has a little too much purple fringing for my tastes, considering it's a modern lens design.

I wanted to get the 31, but the Sigma 35mm Art was significantly cheaper in my country so I got it instead of the FA31. It does have some FF/BF, quite unpredictable. I didn't try to calibrate it since most of the time I'm shooting from a tripod so I have time for manual focus or contrast AF in liveview. The Sigma is big and heavy, but the build quality is very good. When it nails focus, sharpness can be outstanding.

Some samples with the K5IIs (I will get the K-1 as soon as possible so I will probably return to this thread):
