The Viltrox EF-GFX Pro allows you to attach Canon EF/EF-S lenses to FUJIFILM G-mount cameras with full electronic communication. An upgraded version of the original Viltrox EF-GFX adapter, the EF-GFX Pro adds an aperture ring, supports stabilization, and allows you to switch the focus mode from automatic to manual. The autofocus is also faster and more stable. The firmware update port has been changed from micro-USB to USB-C. Additionally, after powering off, the previous settings can be saved on the EF-GFX Pro.
