Summary: The Summilux 15mm delivers high contrast images with very crisp details even with the aperture wide-open. It may not be quite as stunning as the Lecia Nocticron 42.5mm f1.2 in this regard, but it's also a lot smaller and cheaper.
Pros: Sharp, high contrast, well-corrected images. Better than 17mm f1.8., Attractive out-of-focus rendering / bokeh., Good build quality with matching metal lens hood supplied., Manual aperture ring for bodies that support it., Barrel doesn't protrude below base of Lumix GM1.
Cons: More expensive than primes of a similar focal length in range., Manual focusing ring was not always as smooth as I expected., No weather-sealing., Aperture ring redundant for Olympus body owners.
Excerpt: This new wide angle prime lens for Micro Four thirds system cameras sports a fast f/1.7 maximum aperture, Nano Surface anti-reflective coatings, a manual aperture ring and a switch for directly changing between manual and autofocus modes without halving to delve into the camera's menu.
Summary: The fast f/1.7 maximum aperture and associated depth-of-field control are the key features that will attract buyers of this lens since its modest wide-angle coverage is included in all popular kit lenses.
