Cosina has announced a slightly revised version of its ultra-fast normal prime for Micro Four Thirds cameras. The Voigtländer Nokton 25mm F0.95 Type II gains an aperture ring mechanism that is switchable between clicked and clickless operation, a desirable feature for movie makers (and previously seen in its 17.5mm F0.95 and 42.5mm F0.95 stablemates). The optics are unchanged, but the updated lens is slightly heavier and larger in diameter. It will be available in March.
