Use both Konica Auto-Reflex SLR and Leica M Rangefinder lenses with Fujifilm G-mount cameras via the Fotodiox Pro Lens Mount Double Adapter. With the adapter, you can focus the lens at infinity and adjust the diaphragm opening manually. The adapter lets you select the aperture priority or manual exposure mode available in the camera. If there is no aperture dial on the lens, the adapter stops it down to the lowest f-stop limit. The adapter fits tightly to the lens without leaving any gap to prevent unwanted movement during adjustment. This Fotodiox adapter has an all-metal design with a chrome-plated mount.
