Portrait with an old lens?

Hello
I like to make some big and high quality portraits 20X16 (500mmX400mm) with old manual M42 lenses (Pancolar 50/1.8 and Sonnar 135/3.5 ) by using adapter . I need to know if the use of Samsung NX 1000 ,20MP can make big difference than my Pentax K-X ,12MP or not.

None at all - the Pentax is a DSLR, though.
