Specific lens compatibility
Per-lens notes for the Metabones EF-E Mark V based on the vendor's published compatibility chart and community-tested behaviour. Three states: works (✓) — full AF / IS / aperture behave as native; partial (⚠) — usable with a documented caveat; issue (✗) — known incompatibility or rough edge.
| Lens | Status | Note |
|---|---|---|
| Canon EF 24-70 mm f/2.8L II USM | Works | Reliable PDAF + Eye-AF on a7 IV / a7R IV with v0.79 firmware. One of the most-tested EF-on-Sony combos. |
| Canon EF 100-400 mm f/4.5-5.6L IS II USM | Works | IS pass-through and continuous-AF tracking work for slow-subject wildlife on a9 / a9 II once v0.79 is installed. |
| Tamron 70-200 mm f/2.8 Di VC USD G2 (EF) | Partial | Added to Metabones' chart in v0.69. AF works for single-shot and slow continuous; VC pass-through is reliable but bursty tracking lags the native FE 70-200 GM noticeably. |
| Sigma 50 mm f/1.4 DG HSM Art (EF) | Partial | Works but Metabones explicitly recommends the Sigma MC-11 for Sigma EF Art lenses — Sigma's own firmware track is deeper for their lens lineup. |
Common questions
- How does the Metabones EF-E Mark V compare to the Sigma MC-11?
- Metabones has a broader certified list (Canon EF + Sigma + Tamron). Sigma MC-11 is deeper for Sigma's own EF Art / Sports lenses. AF speed is comparable on most modern EF lenses; firmware update cadence is similar.
- How do I update the EF-E Mark V's firmware?
- Plug a micro-USB cable into the side port and run Metabones's updater on Windows or macOS. No body, lens, or dock required — the adapter alone connects.
- Does it support continuous-AF and Eye-AF on the a7 IV or a1?
- Yes — phase-detect AF and Sony Eye-AF subject tracking work on PDAF-capable bodies. v0.69 refined tracking, and v0.79 added a1 / a7s III / a7R IV / a9 II specific tuning.
