The Fotodiox Pro Lens Mount Adapter allows the attachment of Canon EOS EF and EF-S DSLR lenses to Fujifilm G-mount GFX mirrorless cameras. After the lens is fitted to the camera via the adapter, you can achieve infinity focus and control the aperture manually. The aperture priority mode can be chosen for exposure metering apart from manual mode. This adapter offers a perfect fit to the camera without leaving any gap. The all-metal construction and chrome-plated brass mount of the adapter provides a secure attachment.
