Excerpt: Nice, handy, and very mobile little lens, Oly's first offering in m43. Overshadowed by the Pany 20mm, it has nevertheless held its own and delivers equally great results. The only big con is that it's useless for video (very noisy).
Pros: Consistent Output, Durable, Easily Interchangeable, Fast / accurate auto-focus, Lightweight, Strong Construction
Great Lens that is often criticized for being slow

Summary: I picked this lens up as a bundle with Pen E-P1 camera. I had my skepticism as I read many reviews that talk negative about this lens on the web. Well, it proves that you can't judge something until you use it yourself. I really like this lens.
