Summary: This lens is a must if you are replacing a bad lens. I currently use the E-500 and this is a gem. I love it more so, since it has a fairly wide angle for pictures but more so since I can engage a manual switch on the lens and not rely on power manual focus. It focuses quickly and pictures are clear with little noise.
Summary: I am enjoying the lens. At least to my eye the pic are as good as the kit lens that I got with the Olymps E-500 camera. The macro capabilities are good if you are not taking pics of a pinhead. Service from BH was excellent.
