Fringer camera lens adapters
Fringer is the Chinese third-party that specialises in EF-onto-non-Sony bridges — its niche is exactly the gap that Sigma and Metabones leave open. The EF-FX Pro II (2020) is the most reliable EF-on-Fujifilm-X adapter for phase-detect AF, and the EF-GFX Pro (2019) puts EF lenses onto Fujifilm GFX medium-format bodies (with image-circle vignetting on the 44 × 33 mm sensor — users typically switch to 35 mm capture mode). Both update over USB and have continued receiving firmware revisions for years post-release.

The reputable Canon EF / EF-S → Nikon Z autofocus adapter — drives AF (AF-S / AF-C / AF-F, single-point through subject-detect), electronic aperture, optical IS and EXIF passthrough. Single-shot AF is close to native; continuous-AF and high-burst tracking run a notch behind native Z glass and can be firmware-dependent.

Common questions
- Is Fringer firmware still being actively updated?
- Yes — Fringer maintains firmware for the EF-FX Pro II and EF-GFX Pro on its support site, with revisions tied to new Fujifilm X / GFX body generations. Recent updates have addressed PDAF compatibility with the X-H2 / X-H2S / X-T5 stacked-sensor line and GFX 100 II / GFX 100S II. The firmware tool is a small Windows / macOS executable; the adapter flashes over the USB-C port on its body-side, with no involvement from lens or body. Update cadence is roughly twice a year.
- How does the Fringer EF-FX Pro II compare to Sigma MC-11 for AF?
- Different ecosystem, similar tier of AF preservation. The EF-FX Pro II is the canonical EF → Fujifilm X bridge with on-sensor phase-detect AF — that's the route Sigma doesn't offer (no Sigma EF → FX adapter exists). Compared head-to-head on similar bodies, EF-FX Pro II's AF speed with USM EF lenses is closer to native FX glass than the Sigma MC-11 on Sony E with the same lenses, partly because Fujifilm's PDAF rules are kinder to third-party adapters than Sony's. For static and slow-moving subjects, native-like. For tracking sports / birds-in-flight, still slower than a native XF lens.
- Can I use the Fringer EF-GFX Pro on full-frame GFX bodies without vignetting?
- The GFX sensor is 44 × 33 mm — larger than the 36 × 24 mm full-frame image circle most EF lenses are designed for. So yes, mounting a typical EF full-frame lens vignettes on GFX in 44 × 33 capture mode. The standard workaround: switch the body to '35 mm format' / crop mode, which crops the sensor to the EF lens's image circle and gives a no-vignetting capture at ~30 MP (on GFX 100 / 100S) instead of the native ~100 MP. Some EF lenses with image circles wider than 36 × 24 mm (e.g. specific TS-E tilt-shifts, some 17-40 / 16-35 ultrawides) cover most of 44 × 33 in practice — verify per-lens at fringer.org's compatibility chart.
