Japanese optics manufacturer Kowa has unveiled three new 'Prominar' lenses for the Micro Four Thirds system. The Kowa Prominar 8.5mm f/2.8 MFT is a 17mm equivalent rectilinear lens with a surprisingly low amount of geometric distortion (0.12% barrelling). The Kowa Prominar 12mm f/1.8 MFT is a fast 24mm equivalent wide-angle lens, whilst the Kowa Prominar 25mm f/1.8 MFT is a 50mm equivalent "normal" prime. All three lenses have proper distance scales and aperture rings. Availability is slated for Summer 2014.
