One of the best lenses for m4/3. Tremendous sharpness even at f1.2, amazing depth of field, and very fast auto focus. I have been using it for the past 5 years for portraits and I am extremely satisfied. Compared to the 42.5 f1.7 (which I also had), it's like day and night.

Whoever acquires or works with it will understand what it is all about! Premium, heavy construction, the focus by wire focusing ring works exactly like the rest of the lenses without electronic focusing! Fast in everything, exceptional depth of field! One of the best lenses for M43!
