I'm mostly view-camera illiterate, so I'm sure a more informed voice could chime in here, but I'm seeing that "maximum coverage" is achieved on some lenses only when stopped down significantly. On a camera with rise, swing and tilt capability, I'm guessing that "maximum coverage" could only be achieved with the lens and film back parallel (I'm sure someone will correct me if that is inaccurate).
With regard to the 35mm lenses, yes, the Pentax Forums lens database lists the FOV for horizontal and diagnonal for both 35mm full frame and APS-C sensors.
