Megadap ETZ11 vs ETZ21 Pro — what's the difference?

The ETZ11 is the original 2021 model; the ETZ21 / ETZ21 Pro are the 2022+ successors with a broader maintained lens-compat list, faster firmware cadence, and refined subject-detect tracking on Z8 / Z9. The ETZ11 still works well for native Sony G / GM glass on Z6 II / Z7 II — a good used-market buy for that kit; choose the Pro for the latest Sigma / Tamron coverage and Z8 / Z9 animal-AF.

Does the Megadap ETZ11 autofocus Sony FE lenses on a Nikon Z6?

Yes — it forwards phase-detect AF and Eye-AF for supported Sony FE lenses on Z6 / Z6 II / Z7 / Z7 II. AF speed on native G / GM glass is close to native; third-party lens behaviour depends on whether the lens is on Megadap's firmware compatibility list.

Does in-lens OSS pass through the ETZ11?

Yes — OSS-stabilised FE lenses keep their in-lens stabilisation through the adapter and coordinate with Z-body IBIS. Confirm the body's focal-length entry for IBIS if a particular lens doesn't report it.

Megadap ETZ11 — Sony E → Nikon Z adapter

Megadap's first-generation Sony FE / E → Nikon Z autofocus adapter (2021), the budget predecessor to the ETZ21 / ETZ21 Pro. Forwards phase-detect AF, Eye-AF, electronic aperture, EXIF metadata, and in-lens OSS to the Z body.

What this adapter preserves

Compatibility for Sony E lens on a Nikon Z body (computed from the lensmount dataset — open the Sony E to Nikon Z adapter page for the full verdict, flange clearance, and adapter caveats).

Focus: Full AF
IS: IS / IBIS preserved
Aperture: Electronic aperture
Infinity focus: Reaches infinity

What it does

USB-C firmware updates, but the ETZ11's maintained compatibility list is narrower than the later ETZ21 Pro's — native Sony G / GM glass is the most reliable; some Sigma DG DN and Tamron Di III lenses work but lag the Pro's firmware cadence and subject-detect refinements.

Same tight 2 mm flange clearance (E 18 mm → Z 16 mm) as every E → Z adapter — it is a thin ring. Support heavy 70-200 / 100-400 zooms by the lens collar rather than hanging them off the adapter.

Firmware history

v1.02021
- Initial release — Megadap's first autofocus Sony FE / E → Nikon Z adapter
- Phase-detect AF, Eye-AF, electronic aperture, in-lens OSS pass-through and EXIF on Z6 II / Z7 II with native Sony G / GM lenses
v1.12022
- Nikon Z9 / Z fc / Z30 body support added as those bodies shipped
- Expanded the maintained Sony FE lens list and reduced AF hunting on G / GM telephotos
v1.22022
- Select third-party support (Sigma DG DN Art, Tamron Di III) added to the compatibility list
- Final maintenance pass before the 2022+ ETZ21 / ETZ21 Pro took over Megadap's active E → Z firmware cadence

Specific lens compatibility

Per-lens notes for the Megadap ETZ11 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
Sony FE 24-70 mm f/2.8 GM	Works	Native G-Master glass is the ETZ11's strongest case — full PDAF + Eye-AF + electronic aperture on Z6 II / Z7 II behave close to native.
Sigma 35 mm f/1.4 DG DN Art (E)	Partial	Works for stills AF but sits on a narrower, slower-updated compat list than the ETZ21 Pro — continuous-AF and subject-detect on Z8 / Z9 are less consistent. The Pro is the better pick for heavy Sigma DG DN use.
