The brightest F1 lens ever made by Voigtländer is a full-frame interchangeable lens. As an ultra-large-aperture standard lens, it combines a bold styling with a reduced overall length to deliver outstanding performance. To achieve this, the lens employs a ground aspherical (GA) lens element, which allows for the use of high-melting-point, high-refractive-index glass, a process that is more difficult to control in manufacturing than conventional molded aspherical lenses. At the maximum aperture of F1, the lens not only delivers sharp, sharply defined focal planes, but also produces extremely large bokeh effects. GA (ground aspherical) lens element: The first lens element uses a GA (ground aspherical) lens element manufactured in-house. This simplifies the lens construction while maintaining high performance, achieving both high-level image quality and condensed styling despite the ultra-large aperture. A bold and practical style: Despite its ultra-large F1 aperture, the overall length is kept to 55.0mm (from tip to mount surface), which not only reduces vignetting in the rangefinder, but also provides a good balance between the body and lens from an aesthetic standpoint. Beautiful bokeh with 12 aperture blades: The 12-blade aperture is used to make the aperture shape closer to a circle. This results in natural depiction of out-of-focus areas, and point light sources and other objects are blurred in a soft, rounded manner rather than polygonal. Dedicated metal hood included: The included dedicated metal hood has a bayonet-type fitting and can be attached in reverse when stored. This makes it convenient to carry around without compromising the compactness of the camera body. Manual focus for precise focusing: The all-metal helicoid unit is machined and adjusted with high precision, and high-quality grease generates just the right amount of torque, providing smooth focusing and allowing for subtle focus adjustments. Bayonet-type VM mount: The lens mount is compatible with the Leica M mount. It is not only suitable for use with rangefinder cameras, but also offers excellent design balance when attached to mirrorless digital cameras via a mount adapter. Equipped with a rangefinder linkage system: The high-precision rangefinder linkage mechanism enables precise focusing even at wide-open apertures. Full-size image circle: The lens has a generous image circle compatible with full-size 35mm cameras. It also boasts a very compact design compared to interchangeable lenses for SLR cameras.
