this page has a convenient calculator for diffraction limit of a sensor given it's MPix and dimensions. it shows that a 1/2" sensor with 16MPix becomes diffraction limited at f/2.7, so this slightly bigger one would be limited at around f/3. lens is specced at f/2.8-5.9. results out of anything more than the widest end might be less than spectacular...
