Am thrilled by the genuine small pancake. Super bright. The pictures are really sharp over the entire image. It's pretty small and gets down to my Lumix GF1 class. Will it no longer exchange for the larger, fainter zoom lens. The autofocus is indeed felt a little slower than normal zoom lens, but still afloat for snapshots. Also you can hear the autofocus to work, but so loud I do not feel it, it bothers me, on the contrary, I like it when you realize that there is something going on. Which is why I deducted a star is almost beside the point, but the connection is not so visually plan crafted by the construction as the zoom lens. The first attachment I thought, because what is not true, that's the wrong lens. That was indeed specially developed for the GF1, to keep the camera compact beautiful, I do wonder whether the developer in Japan that could not have otherwise solve. In the pictures on the internet is usually the viewing angle designed so that you do not see the right. By now I've gotten used to it. I'm really satisfied with the purchase and the price. For info: I'm not a professional photographer. The Lumix GF1 and pancake are therefore my main camera, with which I now prefer to take pictures.
