I suggest to consider a better lens instead of camera. K-30 plus 18-135 should be a good couple. I bought K5 plus 18-135 two years ago. Even I have further bought several lens afterwards and it is always in my bag when go shooting photos.
I like Fuji colors but the company does not take care the DSLR market. I compared the pictures between Canon, Nikon, Olympus, Sony and Pentax and finally found Pentax is my preference. Pentax colors has got a one third of reason for me to pick a K5.
This forum provides and excellent
Photo Search by Pentax cameras and lens. You may check if the colors are your favorite.
