According to the MTF curves I've seen, the Pentax is sharper than the Sigma Art, which is an incredible achievement by the Ricoh designers.

Very, very impressive.

There may be situations where the Sigma's background bokeh will be less busy or have less fringing in the outer quarters of the frame, but the Pentax could be remarkable in the central half.
