Adapter for connecting EF lenses to GFX cameras. A high-performance electronic mount adapter that allows Canon EF mount lenses to be used with FUJIFILM GFX series medium format cameras. Supports Auto Focus (AF): Enables the use of the EF lens's autofocus function on GFX bodies. While models like the GFX 50S II use contrast AF, practical AF is possible with many EF lenses. Electronic Aperture Control: Equipped with an electronic aperture ring on the adapter body, allowing aperture adjustments with the same feel as GF lenses (1/3 stop increments). High Compatibility: Supports many electronic functions such as aperture control, in-lens image stabilization (IS), and EXIF information recording, allowing EF lenses to be used at a high level on GFX cameras. High-Precision, Robust Design: Features a brass mount and a metal body, providing excellent stability when attaching large and heavy EF lenses. Firmware Updates: Includes a USB port for firmware updates, allowing for future compatibility with new GFX bodies and EF lenses. By using this adapter, you can enjoy your high-performance Canon EF lenses or your affordable and extensive EF lens collection with the FUJIFILM GFX medium format sensor (large format). By attaching EF lenses with an image circle larger than full-frame, you can maximize the descriptive power of the medium format. [Condition] Used infrequently, with no noticeable scratches or scuffs.
