I am brand new to M4/3, coming from the Nikon DSLR world. I have only 3 lenses with aperture ring and the two 2.8 zooms are the reason I'm getting away from my DSLR (weight and size). However, my 50 1.8 is pretty small and I figure it would make a nice portrait lens (although a little long at 100mm equivalent) and would need to be manually focused. I have ordered an adapter on ebay to try this lens out with my Lumix G5. Does anyone have an experience/advice using this lens?
