The Fotodiox Pro Lens Mount Double Adapter makes it easy to switch between various lenses when using a Fujifilm G-mount GFX mirrorless camera. It offers compatibility with Bessamatic and Ultramatic SLR as well as Canon EOS EF and EF-S DSLR lenses. The adapter is an inexpensive alternative for shift photography lenses. It allows infinity focus, manual aperture control along with exposure adjustment by using the aperture priority or manual mode. The precise fit to the lens ensures no play or gap to prevent wiggling during adjustment. This adapter has an all-metal design with a chrome-plated brass mount.
