Product details
The Techart EF-GFX adapter features autofocus functionality and aperture control, allowing selected Canon EF and Sigma EF lenses to be used on a Fujifilm GFX camera. The aperture of the lenses can also be adjusted on the camera by turning the control ring. The EF-GFX adapter currently supports AF-S mode for shooting and the lens image stabilization function (if available). Focal length and aperture data are stored in the adapter.
Techart is currently working on unlocking the AF-C video function, which is expected with a future firmware release. The adapter's firmware is user-expandable and can be easily updated by connecting the adapter to a computer via a Micro USB cable using the update program. The short flange distance of the Fujifilm GFX 50S provides a good foundation for attaching various lens mounts. Although not every full-frame EF mount lens has a large enough image circle to cover the GFX sensor, the Techart EF-GFX adapter still opens up a wide range of lens options that GFX users can consider.
