What this adapter preserves
Compatibility for Canon EF lens on a Fujifilm GFX body (computed from the lensmount dataset — open the Canon EF to Fujifilm GFX adapter page for the full verdict, flange clearance, and adapter caveats).
- Focus: Partial AF
- IS: Lens-only IS
- Aperture: Electronic aperture
- Infinity focus: Reaches infinity
Format note: Lens image circle (full-frame) is smaller than body sensor (medium-format) — expect heavy vignetting or black corners. Many bodies auto-crop to the smaller format and drop resolution accordingly.
What it does
Firmware-updatable via USB to track new EF lens releases.

Common questions
- Will EF lenses cover the GFX 44×33 mm sensor?
- Some do, most don't — most EF lenses are designed for the 24×36 mm full-frame circle. Common workaround: engage the GFX body's 35 mm capture mode to crop in-camera, or accept vignetting for creative effect.
- Does AF work on the GFX 100 II?
- Yes — v1.50 firmware added GFX 100 II compatibility and Eye-AF stability improvements. Phase-detect AF works on the curated EF lens list.
- Which EF lenses are best for the GFX sensor?
- Sigma Art primes (35 / 50 / 85 f/1.4 DG HSM Art) often cover the larger image circle better than the equivalent Canon L primes. Always cross-check the Fringer compat chart before purchase.
