Japanese optical company Kowa - best known for its spotting scopes and binoculars - has revealed that it plans to make three lenses for Micro Four Thirds cameras. The Kowa Prominar 8.5mm F2.8 MFT, 12mm F1.8 MFT and 25mm F1.8 MFT will all feature manual focus and aperture control, and use low-dispersion XD glass and aspheric elements to minimise distortion and aberrations. Other details are sparse at this point, but the lenses are due to be released in summer 2014.
