The Pro Fusion Smart Auto-Focus Adapter for Canon EF- or EF-S-Mount Lens to FUJIFILM G-Mount GFX Camera from FotodioX allows a Canon EF- or EF-S-mount lens to be mounted onto a FUJIFILM G-Mount GFX camera. While doing so, the adapter is designed to support electronic communication between an attached camera and lens. If the lens includes autofocus, image stabilization, as well as camera-controlled aperture functions, this adapter is intended to allow those features to be used. If an attached lens is also capable of generating Exif metadata when used with a directly compatible camera, this Pro Fusion Smart Auto-Focus Adapter is designed to allow that information to be saved along with image files generated with a combination of the lens, a FUJIFILM G-Mount GFX camera, and the adapter.
By enabling camera-controlled aperture functions for a Canon EF or EF-S-Mount Lens when used with a FUJIFILM G-Mount GFX camera, program and aperture-priority modes, as well as shutter-priority and manual modes, can be used through the camera. Power for these functions is transferred from the camera to the lens, while two switches along the side of the adapter for toggling between the camera's program and aperture-priority modes, as well as the camera's 4:3 and 3:2 aspect ratio settings. Alternatively, the camera can be configured to enable the adapter to toggle between the camera's manual and shutter-priority modes, as well as the camera's 3:2 aspect ratio setting and another aspect ratio selected within the camera body.
When an image is taken with this Pro Fusion Smart Auto-Focus Adapter, a matte black internal coating minimizes the potential for reflections within the adapter barrel, which could otherwise result in unwanted glare within the image. This adapter is constructed from aluminum alloy for durability while minimizing weight, and its mounting rings are made with brass to further prevent wear-and-tear.
