<p>You mentioned Hasselblad or Pentax in the subject. I am assuming you are talking about film rather than digital. If you are thinking about digital then just stop reading now :) Any Hasselblad other than the H series will be used. And even if the V series was available new, there would be no real reason to buy one new when so many excellent examples of them are available on the used market.</p>
<p>I also don't think Pentax has a medium format camera available new anymore.<br>
But really, with these all mechanical film cameras there doesn't seem to be any reason to purchase new even if available. Even a forty year old Hasselblad 500 C/M will probably still be working long after the last Hasselblad H5D has ceased to work. </p>
