What has to be factored in is the peculiar photographic culture of Pentax.
Both the Pentax 645 film camera and the Pentax 6x7 scared hell out of every medium format slr company out there until it became clear they
would not offer them with Polaroid backs. Despite the clamoring from working pros, they steadfastly refused.
The Polaroid back of digital is shooting tethered, less true with live view. If photographers can get it to shoot tethered with non-Pentax software,
which I'm sure they can, the point is somewhat moot.
The other issues are leaf-shutter lenses in focal lengths useful to people who use flash-fill outdoors and persuading Schneider--or Hartblei--to make
their 120 TS Makro in the Pentax mount. Their other TS lenses are offered for Canon, Nikon, Pentax, Sony, so why not Phase One and Pentax?
If they do this, they're highly competitive on many different levels, wedding/portrait, still-life studio, nature. My gut feel is that Pentax may not do
those things, and the photographer is forced to hope they offer leaf-shutter lenses and TS lenses sometime soon.
My experience is: if they don't offer them NOW, don't assume they will in time to do you any good.
