Summary: I use this for video, and while it may not produce the "sexy" image quality of some of the faster Olympus/Pany lenses, this is a great lens to have. Very fast auto-focus, great image quality. I can see myself using it in a lot of different situations and will probably end up using more than my Olympus 25mm f1.4 going forward.
Summary: It's not my walk around lens - that's the Lumix 25mmk f/1.4 Leica lens on the Oly EM1. But I carry this 14mm in a pocket and thus never miss a shot requring a wide field of view. Very sharp images. Bought it used from Asia via Amazon. Very satified.
