For me disappointing

Since then, I take pictures, this is done only with Pentax, starting with the wonderful ME Super from the 80s. After that had or have my wife and I a lot of DSLR, Pentax what so lent, from the istDS, then the K10, K20, Kx. Until 2 weeks ago I was working with the K 5 and was for 4 years very satisfied, my wife has a K 30. Then the burglars came and took my 5 K with the K 30 they left (ignorant).
For me it was clear that it is now time for the legitimate successor of the K5. So I ordered the K 3 and thoroughly tested. And much of what I had hoped for is not arrived.
With and without low-pass filter I have now tried for 7 days to shoot clear photos, I am not able even with the best lighting conditions. Either JPEG still in RAW format Everything looks washed out and low contrast, or simply out of focus, and not just at the edges. The monitor shows me serially crisp, brilliant photos, but when I look at the photos on my computer, it seems to me, as I have the wrong glasses on.
To be sure that it is not perhaps because of my computer, I have series of comparison pictures taken with the K 30, K 20 and K 10, which are all still in my possession. Conclusion:
The K 10 below provides the K3 actually ... The K 20 is not, here were my results both on location as well as indoors significantly better than with the K 3. The K 30 but hit my K 3 by far.
Now it may be that I have had bad luck with my model, which I will return tomorrow with a heavy heart. That's why I do not want to condemn the K 3, which has an extensive auto focus, significantly lightened colors than the predecessors in automatic mode, low noise, a great feel here. What use to me but if the lack of low-pass filter much faster Moiré effects can arise as I suspected and monitor clear photos deceives me that does not exist?
Instead, I'm going as a longtime Pentaxianer treat even a change of air and employ me closer with Sony and Canon.
But I would be happy about over reactions. Are there any other buyers who perceive it so as I or did I just caught the wrong device?
