I must say that I really need a lens that can produce awesome bokeh. Can't effort either 14-35 f/2 or 50mm f/2, so I bought the cheapo OM lens 50mm f/1.8. Unfortunately it is old manual lens. The bokeh produced somehow good however not much in 4/3.
With big viewfinder in E-3 compares to E-500, I can easily manual focus. The lens good for portrait & sharp at f/2.8-4.
