The NOKTON 50mm F1 Aspherical is an ultra-fast standard lens for full-frame (Nikon FX format) mirrorless cameras with the Nikon Z mount. It is the fastest standard lens from Voigtländer for full-frame cameras, while a GA (ground aspherical) lens provides a tight, compact style. Optics optimised for the sensors of mirrorless cameras. The lens has a full-frame image circle and can be used with both full-frame (Nikon FX format) and APS-C size (Nikon DX format) mirrorless cameras. GA (grinding aspherical) lens and mechanical components. The GA lens is used as the primary element, while also equipped with a floating mechanism to ensure stable image quality from the shortest shooting distance. This lens is equipped with electronic contacts for communications between the lens and the body. Manual focus for reliable focus operation. Adopting a full-metal helicoid unit processed and adjusted with high precision and high-quality grease that produces an appropriate torque, it enables fine focus adjustment. The aperture diaphragm is configured with 12 blades. This means the out-of-focus areas of images are drawn naturally and point light sources are drawn as soft round bokeh rather than as polygonal shapes.
