Also on MFT still a class of its own!

On this objective, I appreciate the high contrast, the great colors and low distortion. Even the very few top super wide-angle from the KB-camp here find it difficult. This also applies to the new Sony 16-35 / f4, which I have in the near future direct comparison. Only when the lens flares that Olympus is weaker. However, the are a nice stylistic devices and can be, if they occur at all times, eliminate by simple lateral shadowing by hand.

Above all, it is also better than the MFT "colleagues" who have to compromise because of their size.

It can be the way dim with a clear conscience to f13. From the often quoted diffraction blur is nothing to note here. The Schräfe is clean right into the corners and at the level of prime lenses.

The build quality is above reproach, while it is not even that hard. With 2 other MFT lenses and the M1, it fits well in a relatively small camera bag. Those who (used) gets cheaper, it should indulge. The photographs thus obtained are another world and be fun. The new OM-D M5 II 40MP mode should open up a whole new dimension here.
