Cosina, manufactures of Voigtländer, have announced a new 50mm F1.1 lens. Voigtländer makes some very fine lenses and cameras. The lens has the "M" mount for Leica, Zeiss and Voigtländer rangefinder cameras. The digital lens factor makes this about a 66 mm equivalent when used on the Leica M8. The lens will cost $1,149 at Camera Quest. Leica's 50mm f/0.95 Noctilux costs a mere $10,000 at B&H Camera.
Amazing what someone might pay for one f stop of light.
