Seriously, I wouldn't buy a "super-zoom" as I think the quality may not be too super. Although it does depend on the output required. 6" x 4" prints and web use probably will make them OK, but A3 prints for competitions, maybe not...

If you are processing black and white films then I would suggest you do that yourself - this will be relatively cheap and the quality will be as good as your technique. If you could find a good quality second hand film scanner then it would not take too many filns before you were in pocket on the deal. A Nikon Coolscan IV would be a good choice with 2929 dpi resolution. Its 35.5MB files should be more than good enough.
You could even process C41 or E6 films at home, but that is a little more complex than b/w.

The viewfinder is an important feature for me, so I think I will stick with the proper pentaprism of the *istDS.

In general, with such a long lens, there will be problems with sharpness because of camera shake. You would need a very solid tripod and high shutter speeds.
At long distances aerial haze will reduce sharpness and contrast, so a UV filter may help, but it must be of the very highest quality to avoid image degradation.
Using the *istD with a 800mm would result in a 1200mm-equivalent, and this is very long lens territory indeed. I don't know how much experience you have had with such lenses, but I would expect a fairly long learning curve to get the best out of them.

I'm glad you're enjoying your new camera. I think digital photography has improved the standard of photography in general. It has mine for sure.
When you look at photo magazines of say the 1960s or 1970s the pictures are so very often just poor compared with what we see now.
Long may we continue to progress!

With the camera set to manual focus, you turn the focusing ring on the lens until you think the subject in the viewfinder looks sharp....
This works just fine if your eyesight is up to it, but I'm not convinced that it works at all with electronic viewfinders. There are, of course, no Pentax electronic viewfinders!

I'm happy now with the centre point fixed as the focus point.
