9 out of 10 points and recommendedIt's sharp! Wide open! At all focal lengths! Corner to corner! Subjects have pop to it But still a natural rendering of smooth surfaces like skin Natural colour Bokeh mostly impressive Constant f/2.8 Close focussing Extremely versatile Very well bIn some situations bokeh can become somewhat busy Lens is quite large and heavy for for m4/3 but very small and light for what it is!
On an EM-1 this lens is incredible. Easily the most convincing lens I have handled. I was in doubt for a long time if its size would not defeat the size advantage of m4/3 concept and why I moved to the system in the first place. But now I can without a doubt recommend this lens to anyone considering it. Invest in your lenses above cameras is still true for modern digital age.reviewed June 9th, 2018 (purchased for $1,200)
