The Leica Noctilux-M 50mm f/0.95 is a fast lens released by the camera manufacturer Leica in 2008 as a step up from their Noctilux 50mm f/1.0 lens. It features a floating-lens element for accuracy in the close-up range. Leica claims that "Even the light from one candle can be sufficient for handheld photography." It is one of the fastest lenses commercially available, and the fastest for the Leica M mount.
