Looking for a nice portrait lens. Just bought into the OMD system and have the 14mm and 12-50 zoom. I have some old legacy glass I'm using with adapters, the Olympus 55mm 1.2 and Takumar 50mm 1.4. I hear great things about the 45mm 1.8 but how does it compare with I already have if autofocus isn't really an issue for me. I really like the smooth buttery type bokeh. I actually prefer the look of the takumar 1.4 over the oly 1.2 Thanks.
