Canon EF Lens to Fuji G-mount T Smart Expander 1.26x (GFX)
- Make Canon EF mount lens to cover the Fujifilm G-mount (GFX series) camera ;
- Advanced 5-element/3-group optical design incorporating ultra-high index Lanthanum-based optical glass by Caldwell Photographic in the USA ;
- Magnification of lens: 1.26x *
- Crop Factor with Fujifilm GFX camera: 1.0x
- Canon EF mount lens to Fujifilm G-mount camera.
- Autofocus. Phase-detection autofocus (PDAF) is supported no matter which AF lens is used. Adapters support PDAF by translating pertinent metadata about the optics between the lens interfaces. In this way, broad support of the widest range of lenses is made possible.
- Lens iris/aperture is set by the controls on the camera body.
- Optical image stabilization (IS) lens support.
- Smooth iris support with the latest Canon (2009+), Tamron (SP series 2013+) and Sigma (2016+) lens models.
- Focal length and aperture are adjusted in EXIF (see note 3).
- LED indicator shows communication status.
- Powered by camera body. With most lenses, no external power source required.
- The tripod foot is detachable and compatible with Arca Swiss, Markins and Photo Clam ball heads.
- Flocking to reduce internal reflection.
- Aluminum alloy and brass construction with chromium plating.
- Satin surface finish.
- Detachable Arca-Type tripod foot compatible with Arca Swiss, Markins, and Photo Clam ball heads(clamp directly or attach to quick release plate by a 1/4"-20 screw).
* Note: Aperture values decrease by 2/3 of a stop used in conjunction with this Expander.
Metabones Expander 1.26x
The EF - GFX Expander 1.26x allows Canon EF mount lenses to be mounted on Fujifilm GFX camera bodies without getting dark and / or soft corners. The magnification factor of 1.26x perfectly matches the image circle of the full-frame Canon EF lenses to the medium-format sensor of the GFX series cameras, and therefore the diagonal field-of-view (FOV) remains exactly the same.
The optical design consists of 5 elements in 3 groups, incorporating ultra-high index Lanthanum-based optical glass as well as one element made of fused silica, resulting in extremely good performances with professional-grade f/2.8 zoom lenses. For example, a 24-70mm f/2.8 lens becomes a 30-88mm f/3.5 zoom, and a 70-200mm f/2.8 lens becomes an 88-252mm f/3.5 zoom.
Due to the nature of focal extenders, the aperture values decrease by 2/3 of a stop; f/2.8 becomes f/3.5 and f/2 becomes f/2.5. High-speed fixed focal length lenses such as the 50mm f/1.4 will be transformed into a very fast 63mm f/1.8 standard lens for the GFX system.
The EF-GFX mount Smart Expander features Metabones’ electronic integration, including phase-detection autofocus (PDAF), in-body image stabilization (IBIS), optical image stabilization (called IS/OS/VC by various lens manufacturers) and smooth iris. The button on the Smart Expander toggles between auto aperture (programmed exposure or shutter priority) and manual aperture (aperture priority or manual exposure). If a manual lens with no electronics is attached, the button brings up the manual lens selection on the camera body so that focal length can be chosen for correct IBIS operation and EXIF.
- 1. EF-S lenses do not fit on Smart ExpanderTM. Some EF-S lenses may be modified to fit, but do so at your own risk.
- 2. Third-party lenses designed for APS-C format do not have enough coverage when used in conjunction with Smart ExpanderTM.
- 3. Some improperly-made M42 screw mount adapters may short the electronic contacts of the Smart ExpanderTM and cause damage to the Smart ExpanderTM and/or camera body.
- 4. Many manual focus lenses (e.g. OM 28/2.8, OM 50/1.8, Leica R 15/3.5) have rear protrusions (spikes, levers, other appendages) which would damage the optics and/or housing of Smart ExpanderTM. They need to be modified before they can be safely used on Smart ExpanderTM Check and make sure there are no rear protrusions from the adapter/lens combination before using on Smart ExpanderTM. Scratches and damages caused by rear protrusions on Smart ExpanderTM are not covered by warranty.

Since its inception, Metabones has been designing and manufacturing lens adapters recognized among professionals and enthusiasts as leaders in design and workmanship.
Contrary to the popular trend of other factories using an aluminum ring painted black on the camera-body-side, we instead take no short-cut but use precision-machined brass with chromium plating on both the camera-body and the lens sides of our adapters, in order to ensure smooth mounting, great appearance, and durability. The lens side of the adapter features a strong leaf-spring structure, strengthening the adapter-lens connection and ensuring tightness of the lens in order to reduce wear and prevent focus errors and optical alignment issues from appearing.
Metabones uses matte-black treatment to keep internal reflection to a minimum in order to maintain the maximum optical quality possible with the lens.
All Metabones Adapters follow this tradition of uncompromising precision, robust build quality and outstanding finish. Our new Smart AdapterTM series of products add industry-leading electronic interfacing technology from Canada, with true electronic control of the lens' aperture directly from the camera body.
- Both camera-side and lens-side of the adapter are made of brass, precision-machined and plated with chromium.
- Satin surface finish - just like your OEM lens and camera mounts.
- Precise fit and solid connection - lens has no play, gap or wiggling when mounted on adapter and no adjustments are required to fit your lens.
- Designed to reach infinity focus while maintaining the correct registration distance required to maintain optical quality of CRC lenses or lenses with floating elements.
Our Smart AdapterTM series adapters have the following additional features
- True electronic integration of aperture diaphragm - let camera automatically choose aperture in P or S exposure modes, or dial in yourself on the camera body in A or M modes.
- EXIF data such as lens identification, focal length and aperture.
