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; Megadap publishes a maintained per-lens compatibility list covering native Sony G/GM glass plus most Sigma DG DN and Tamron Di III lenses.
Flange clearance is tight (E 18 mm → Z 16 mm = 2 mm), so the adapter is a thin ring. Heavy 70-200 / 100-400 zooms should be supported by the lens collar, not the adapter, on the Z body.

Specific lens compatibility
Per-lens notes for the Megadap ETZ21 Pro 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 70-200 mm f/2.8 GM OSS II | Works | Full PDAF + Eye-AF + OSS pass-through on Z8 / Z9 from v2.0 firmware. Subject-detect AF works as on a native Z lens. |
| Sigma 100-400 mm f/5-6.3 DG DN OS Contemporary | Works | v3.0 firmware specifically refined tracking. Full PDAF + Animal / Bird subject detect on Z8 / Z9. |
| Tamron 28-75 mm f/2.8 Di III VXD G2 | Partial | Added in v2.0. AF works well for stills; video continuous-AF can occasionally hunt — Megadap updates lag Tamron firmware revisions by a release. |
Common questions
- How well does AF work on Sony G / GM lenses through the Megadap ETZ21 Pro?
- Excellent on Z8 / Z9 / Zf with v3.0 firmware — full PDAF, Eye-AF, and Animal / Bird subject detect. Z6 II / Z7 II are also fully supported with single-point and wide-area tracking.
- Does it support Sigma DG DN and Tamron Di III FE lenses?
- Yes — Megadap publishes a maintained compat list covering most Sigma DG DN (Art / Sports / Contemporary) and Tamron Di III lenses. Tamron G2 zooms were added in v2.0.
- How is in-lens optical stabilisation handled?
- Pass-through — the adapter forwards stabilisation commands so OSS-stabilised FE lenses keep their native IS behaviour on the Nikon Z body without conflicting with Z-body IBIS.
