I try to stop down to F/9.0 for shots through the Pentax K-S2.  The harshest test for lenses is the "star" test where point sources and lights at night are arrayed across the field.  What happens at the edge is vastly improved by stopping down perhaps more than you'd be used to with narrower lenses.
