Ok.. technically f/1.1 but who cares. For those that love fast glass, there is a new one coming to market.. and it isn't priced out of this world. Voigtlander/Cosina continues to amaze me with the high quality glass they can bring to market at a fraction the cost of competitors. New to market is a 50mm f/1.1 nokton and the sample photos look nice. Voigtlander lenses still share space with the highly regarded Leica branded lenses in my camera bag.. including 12mm heliar, 21mm color-skopar, 35mm nokton, and 28mm ultron.
