Not true. The difference has absolutely nothing to do with digital or film.
I se no reason at all why the recording media should have any impact on DOF.
It's simply because of the format. That's all. So, you could just say: DOF
is greater for APS cameras (or just smaller formats). Everybody and his
Really?
It's a function of the focal length of the lens (for a given aperture).
Smaller format = shorter focal length "normal" lens = greater depth of
field.
Digital cameras (and APS cameras) are smaller format than 35mm.

Unfortunately a camera of that spec while offering the advantage of FF AOV

what I want is FF DSLR, 10 Mpixel, Focusing Screen, and full K-mount

Yes, and that is why for an equivalent focal lenght you get more DOF
with the *ist than with film. Because a 50mm lens has more DOF than a
75mm lens.

Camera companies in general like to sell new lenses as it makes them
more money, so whilst it is possible I dont think you will find Pentax
