Actually the wording wasn't clear as you didn't specify models and seemed to be lumping the entire line into the hobbyists category. If that wasn't the intent then I misunderstood and apologize. I would consider the D3300 referenced by the OP much more a hobbyist camera when compared to the features of the K50. Moving on up the line the k1 or 645z hardly qualify as hobbyist, any more than would applying the term to top of the line Canon or Nikon. Sorry if I was overly touchy as we Pentax users tend to be seen as the "outsiders" sometimes, despite the side by side comparisons.
