I will buy a dslr for fotographing birds, my Canon S2 is no longer enough for me. K10D seems to be the best cost effective choice, but there is an important problem: Sigma does not produce HSM lenses for Pentax yet. If you buy Sigma 50-500, you will have to use it without HSM. Focusing speed is very important for bird photos, so is the HSM feature.
Does Pentax plan to produce telephoto lenses with ultrasonic motors? I cannot wait for a year, if they will not, I will have to prefer a Canon or Nikon camera.
