Question k-mount adapter

I bought one of the non-aperature K-mount adapters. Even on a tripod, all my images seem grainy, blurry, yet "soft". Does not seem to be any difference between my newer DA lenses and legacy lenses.

What gives?

Hopefully the adapter keeps the lenses wide-open rather than at minimum aperture. Because if you're shooting stopped down beyond F5.6 or so, diffraction will obliterate your image quality.
