Hello, How are you? So, I'm thinking about adding a new lens to my mu43 kit... I've made my mind on a fixed focal length lens and the 45mm (90mm equivalent), looks right to me... So now, my question: Olympus 45mm 1.8 or Panasonic-Leica 45mm 2.8? Which would you prefer? How different is the DOF between 1.8 or 2.8 on a portrait? Is it too noticeable? How about low light? Thank you. Regards!
