I have the Voigtlaender 40/1.4 on a NEX-5 and from my pictures(no test charts) I would say it is a little bit softer at 1.4 but still very usable. The Bokeh is sometimes harsh for high contrast backgrounds but mostly it is smooth enough. I would say it is a little bit better than the Sony 50/1.4 in every respect. The 40/1.4 has also a little focus shift.
