Photozone posted their full Kowa Prominar 25mm f/1.8 MFT lens review:

The Kowa Prominar MFT 25mm f/1.8 faces a difficult task especially given its price tag of 800US$. The 25mm segment is covered by a variety of lenses which are either much faster, much cheaper or both. However, the Kowa lens has at least one advantage – optical performance. The image quality is decent at max. aperture but when stopping down it is about as good as it gets on the micro four thirds system.
