The K 01 I use exclusively with my old Pentax K lenses. The manual focus is very straightforward by Lupe - no AF-pumps or -Surren. It can be discreetly take pictures with it. The sound "box" with old lenses bothers no. The picture quality is above reproach, because many new lens has to hide. The rubber flap does not bother me. They stuck when I want it. The battery lasts a long time, and use the K 01 is not a problem. As a digital body of my old equipment ideal. Overall, a "great success" of Pentax (Courage to design !!!!) unfortunately not enough enthusiasm triggered - a pity! Perhaps in many years even a real art object?
