.......anyone can shoot clear pictures. Using the camera to see what you want the world to see, blurry, fuzzy, sharp......it happens with photographers who know their gear inside and out. Pentax is one of the best values for the money and their lenses are world class. The k-x is not a pro level camera and it would not be the body you would use if you were to go pro. But the k10, k20 and k7 are, and the lenses you will use and fall in love with on your k-x will be ready to go when you buy another Pentax body. Not so with Canon, Nikon, Olympus or Panasonic.
Good luck with your choices and enjoy shooting
