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). Optics are same, but the updated lens is slightly heavier and larger in diameter. Lens will be available in March.
Second version of this 25mm Voigtlander lens is a nice improvement. Those shooting video will appreciate the option for a stepless aperture and everyone will enjoy the fast maximum aperture and ability to isolate a subject from their surroundings with shallow depth of field.

At maximum aperture, the image quality is ok, but far from perfect. It’s not really that sharp, and you can see quite a bit of light bloom around high contrast areas. But keep in mind this is quite normal for most of the super fast lenses. Even the lens with a much higher price tag has similar issues and the Voigtlander 25mm isn’t doing too bad in comparison.
