after having used the k100d a fair bit i would have to say that it was one of the worst cameras i have ever used, the AF was slow and useless(it was faster for me to manule focus 95% of the time), and the auto white balance was terrible, how ever the build quality is fairly good for a entry level camera. so my experiance with Pentax was fairly terible. however the image quality was preety good, but not as good as canon or nikon.
