Pentax normally has a pdf manual online for these. I get a not found on the link from the Pentax USA site, haven't looked at other countries.
I have a 2-xs. I haven't played with it much, but I've used it on a 28-300 Tamron zoom and even on a 500mm f/8 mirror lens. I sense it will take a while/lot's of practice and good luck to get good results. I'm sure it's doable. The biggest problem I see it the loss of effective aperture, and low light in the viewfinder. All depends on conditions of course.
