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.
Summary: This lens at the white-box price is great value and a nice light lens for when I'm bringing my camera out in social situation where I don't want to carry a lot of gear. 14mm is a bit wide but is also great indoors when trying to capture group shots. The item arrived within the stated time, even over the Christmas holidays, and was well-packed. I had no issues at all.
