The FotodioX PRONTO Autofocus Adapter for Leica M to Nikon Z-Mount Mirrorless Cameras is designed to enable the use of Leica M-mount lenses on select Nikon Z-mount mirrorless cameras. This adapter not only allows for the compatibility of different lenses but also enhances near-range portraiture by enabling closer focusing than the lens's normal minimum focus distance. By creating space between the camera body and lens, the focusing distance is reduced, resulting in a magnified effect on the subject. Moreover, this adapter can be used in combination with separate lens to Leica M-mount camera adapters, making it possible to use lenses of other types as well.
To control focus, the adapter includes a built-in helicoid mechanism that extends and retracts the compatible lens based on the autofocus capabilities of the connected camera, whether it is contrast detection AF-S or AF-C. Constructed from a blend of brass and aluminium alloy, the adapter is designed to support infinity focusing and features a brass lens mounting ring for a durable and lightweight connection between the camera and lens.
