Just done some quick comparison tests and I am struggling to see much difference. Maybe I will test again with a portrait subject...

F 50mm at 1.8




DA 50mm at 1.8




F 50mm at 1.4

- just based on those two f1,8 shots - I actually think the bokeh is tiny bit smoother with the DA 50/1,8 while F50/1,4 has a bit crisper colours....but I am spliting hairs here
