Must have for MFT

Every photographer, no matter what system, knows the following phenomenon. You usually have one or two in your backpack and on every bodys bodys hangs a lens. Oddly, everyone has to be so "Always plan" which he really does not change. While I've always 12-60 on a 3-D, I've been on the E-P2 always the 20 / 1.7. It is as if it had grown there firmly. Now and then I of course also use other lenses, but basically it is always the 20s by Panasonic.

Reasons for this are manifold.
1) The focal length (optimally at least for me). Converted 40mm comes in almost any situation!
2) Absolutely brilliant picture quality. Even with an open shutter the image is absolutely sharp! And thanks to the K-AF of PEN, the focus actually always hits the right spot.
3) The compactness of the lens is overwhelming. At a PEN it actually looks like from the 1950s. At the G2 it carries virtually no longer because of the hump and the handle just have the same depth.

However, each lens has its drawbacks. In this case, it is speed. Fail the AF is always. But he needs a tick longer than for example the Olympus 14-42IIR. For me, however, not bad because it has not yet so was significant.

In my view, can such an objective only 5 star cash. It will be for most people a "Always top" and offers absolutely unbeatable image results at an unbeatable price. The lens is unique in its performance and its design and deserves my absolute recommendation.
