Gain macro capabilities with your Mamiya 645 lens by mounting it to your FUJIFILM G-mount camera with the DLX Stretch Adapter from FotodioX. It features an integrated focusing helicoid that provides close-up focusing when desired and can be retracted for guaranteed infinity focus during general purpose shooting. For added light control, this adapter also includes internal filter threads which allow separately available 49mm neutral density filters to be screwed in behind its mount for the FUJIFILM G camera. Additionally, this adapter features a precise construction with chrome-plated brass mounts that securely hold the lens and camera in place. A soft case for the drop-in filters is included.
