SMC Pentax-A 24-50mm f4
SMC Pentax-FA 24-90mm
These will give excellent results.

But there is a catch. The smaller sensor is definitely more susceptible to noise, so although sharpness is not an issue noise will be if you up the ISO rating. I would recommend using these cameras at their lowest ISO, and not allowing any auto-ISO function to operate.
Gradation in smooth areas of tone will also be not quite as smooth, another by-product of the smaller sensor, but there is no escaping that.
Having said that, you would only notice these effects if you do indeed make A3 prints. If you only make A4 prints or only upload to the web, then there will IMHO be no problem.
Personally I am very pleased with my personal choice of the 750Z. Sue is delighted with her S5i, but I find it too small.

And seeing I replied first, you don't even need any justification!

I don't meddle inside cameras, I leave it to those who know what they are doing....

If you need correction to see the image clearly there are a range of dioptre adjustment lenses available that will correct the image so you can focus your eye in the right place. Your optician will be able to tell you what value you need. I think they are available from -5 to +2.
For most of these cameras I find that wearing the glasses I use for the computer screen enables me to focus with ease.
More modern cameras have a built in dioptre adjustment on the eyepiece, which is very useful.

But, apart from me being over-predantic, you are absolutely right and all K mount bodies can use the adapter.
It extends the life of your screw thread lenses enormously.

I use Photoshop 7, but am about to upgrade to CS2. There are some very useful features that are not in Elelments, but having said that Elements is considerably less expensive and does an excellent job.
Maybe someone else has a favourite alternative?

Personally, I have never been happy with the results from teleconverters, although I do agree that they can have their uses.

So I have no direct experience, but I would guess that it would produce good results. The downside of that is that the lens is big, unwieldy and very expensive to keep in filters!
However, if I ever found one at a reasonable price i would buy it...
