Voigtlaender Voigtlander Nokton 40mm f/1.2 Lens for Leica M, Black BA342A

NOKTON 40mm F1.2 Aspherical Full Frame LensThe NOKTON designation is only given to high-speed lenses in the Voigtlander lineup with a maximum aperture of F1.5 or faster. When the first NOKTON was released in the 1950s, it was positioned as a lens that enabled images to be captured even in low light. However, with constantly improving imaging sensor sensitivity, the advantage of a high-speed lens nowadays is the ability to use as a means of photographic expression the out-of-focus bokeh created by opening the aperture.The NOKTON 40mm F1.2 Aspherical VM features two elements each with two aspherical surfaces, so you can enjoy reliable optical performance from maximum aperture and gentle very out-of-focus bokeh. This lens shares the same optical configuration as the NOKTON 40mm F1.2 Aspherical E-mount lens, however the NOKTON 40mm F1.2 Aspherical VM is optically adjusted with consideration for use on both film and digital and features a focus-coupling cam that enables focusing with optical rangefinders.This lens is focus coupled down to 70cm (varies lightly depending on the camera) and can focus down to a minimum distance of 50cm on digital cameras with a live view function. Furthermore, even though the lens has a large F1.2 maximum aperture, it realizes a very compact style with a weight of just 315 grams (lens on its own) for very light handling.The 40mm Viewfinder M optical viewfinder with metal body is also available as an option for the NOKTON 40mm F1.2 Aspherical VM for use on rangefinder cameras that do not have a built-in 40mm frame line.
