If you look at his history on the site you will see such an
enthusiastic review of the Pentax.  It is his personal camera. He
bought it because he liked it. It improved on his experience with older
Hasselblads and his Rollei 6008. He made money with it. (Whether he has
broken even on it is another question. :-)  ) He knows how to use it. I
think he was just bowled over by results with the Canon. And he is not
just a digital maven.  He really trashes the Nikon Coolpix 5700 in the
review on his site.

As to shutter disturbances of a large focal plane shutter.  Since it is
difficult to take a picture without engaging the shutter, does it
really matter what degrades the picture? You can see from his site that
this guy is careful.  You don't think he would have noticed a softened
image from his previous equipment with Zeiss lenses and Compur shutters
when he got the Pentax. What he said is very believable to me.
