Does the FTZ II adapter preserve autofocus on Nikon F lenses?

Yes for AF-S and AF-P lenses (motor lives in the lens) — full AF, VR, and electronic aperture all work on every Z body (Z9, Z8, Z7 II, Z6 III, Z5, Zf, Z50 II, Z30, Zfc). For AF-D and earlier screw-drive lenses, no — the FTZ II has no built-in screw-drive motor, so they become manual-focus with focus-confirm only. The original FTZ I and FTZ II differ only in tripod-foot construction; AF capability is identical.

What's Nikon's 58 mm f/0.95 Noct and why is it Z-mount only?

The Noct is a manual-focus, all-electronic 58 mm f/0.95 prime that exploits Nikon Z's unusually wide 55 mm throat and short 16 mm flange — geometrically impossible on Nikon F's 44 mm throat. Released in 2019, it's Nikon's flagship halo lens demonstrating the optical headroom Z's mount geometry allows; no AF, focus-by-wire only.

How does Nikon Z compare to Canon RF and Sony E for mount geometry?

Z's 55 mm throat is the widest of the three (RF 54 mm, E 46.1 mm) and its 16 mm flange is the shallowest (RF 20 mm, E 18 mm). The wider throat plus shorter flange gives Z the largest design envelope for fast, wide-aperture lenses — but the practical advantage is small for most photographers, and Z's third-party native lens count lags behind both RF and E in 2026.

Nikon Z — flange distance, protocol, and adapter compatibility

Nikon's full-frame mirrorless mount. 55 mm throat (the widest of any current mainstream mount) with a 16 mm flange enables exotic optics like the 58 mm f/0.95 Noct. The FTZ II adapter mounts F-mount lenses with full AF on AF-S and AF-P; screw-drive AF-D lenses become manual-focus with focus confirm.

Nikon Z on the flange-distance axis

Nikon Z sits at 16 mm — highlighted in orange below. The flange-distance gap between the mirrorless and SLR clusters is the room a mechanical adapter occupies; that gap is why almost every SLR lens adapts onto every mirrorless body, and why the reverse is mechanically impossible.

Lens mount	Result	Adapter examples	Caveats
Lens mount Canon EF flange 44 mm	Mechanical AF partialIS fullAp. electronic	Fringer EF-NZ II	EF is a fully electronic mount with no aperture ring — a glassless mechanical ring leaves the diaphragm stuck wide open and gives no AF. The path that works is the electronic Fringer EF-NZ II (FR-NZ2), which drives AF, 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. No screw-drive EF lenses exist — all EF AF runs through the in-lens motor.
Lens mount Canon EF-S flange 44 mm	Mechanical AF partialIS fullAp. electronicvignettes	Fringer EF-NZ II	EF-S is electronically identical to EF, so the Fringer EF-NZ II drives AF, electronic aperture and IS on EF-S lenses exactly as on EF. EF-S's APS-C image circle covers only APS-C — on a full-frame Z body (Z6 III / Z8 / Z9) the camera shoots in 1.5× DX crop mode or vignettes; native coverage only on APS-C Z bodies (Z50 / Zfc / Z30).

Adapter SKU teardown

Curated adapter SKUs that involve the Nikon Z mount on either side, with the operational specifics — body-side electronic contact count, firmware-update path, weather sealing, and whether optical glass is in the path.

Nikon FTZ II
released 2021
Nikon F lens → Nikon Z body
- 11 body-side contacts
- no firmware updates
- weather sealed
- no glass — pass-through
- Replaces the original FTZ; loses the tripod foot for clearance with super-telephotos. AF preserved on AF-S and AF-P lenses; screw-drive AF-D becomes manual.
- Required for any F-mount lens on Z-series bodies — there is no third-party AF F→Z adapter.
Nikon FTZ (original)
released 2018
Nikon F lens → Nikon Z body
- 11 body-side contacts
- firmware updatable
- weather sealed
- no glass — pass-through
- First-generation F→Z adapter shipped alongside the Z6 / Z7 launch. Mechanically identical to FTZ II for the lens-side mount; the visible difference is a removable Arca-style tripod foot on the underside.
- Firmware updates are pushed by the Nikon body's firmware-update mechanism over the Z protocol — no separate USB port. Z body owners running the latest body firmware get the latest FTZ behaviour automatically.
- Still preferred over FTZ II by users mounting heavy AF-S super-telephotos (200-500 / 500 f/5.6 PF / 600 f/4) because the tripod foot offloads the lens's tail from the Z body's mount.

Megadap ETZ21 Pro
released 2022
Sony E (incl. FE) lens → Nikon Z body
- 11 body-side contacts
- firmware updatable
- not weather sealed
- no glass — pass-through
- Sony FE / E lens onto a Nikon Z body with full PDAF + Eye-AF, exposure metadata, in-lens IS pass-through, and electronic aperture.
- 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.
Firmware history
1. v1.02022
  - Initial Pro release — Sony FE G / GM + Sigma DG DN compatibility on Z6 II / Z7 II
2. v2.02023
  - Z8 / Z9 Eye-AF subject tracking compatibility
  - Tamron 28-75 G2 and 70-180 G2 lens entries
3. v3.02024
  - Animal / Bird subject-detect AF on Z8 / Z9 / Zf
  - Sigma 70-200 f/2.8 DG DN Sports and 100-400 DG DN tracking refinements
Approximate milestones — verify against the Megadap firmware page for the authoritative changelog.
Techart TZE-01
released 2022
Sony E (incl. FE) lens → Nikon Z body
- 11 body-side contacts
- firmware updatable
- not weather sealed
- no glass — pass-through
- Direct competitor to the Megadap ETZ21 — same purpose (Sony FE → Nikon Z with AF) at a slightly lower price point.
- Firmware updates via micro-USB; Techart's compatibility list is shorter than Megadap's and Tamron + Samyang AF lenses sometimes lag a firmware revision behind.
- Same 2 mm flange-clearance constraint — a thin ring; combine with a tripod-collared lens for any glass beyond ~1 kg.
Firmware history
1. v1.02022
  - Initial release — Sony FE G / GM on Z6 II / Z7 II with basic Eye-AF
2. v2.02023
  - Z8 / Z9 compatibility — single-point + Wide-area AF tracking
  - Sigma DG DN compatibility entries added
3. v3.02024
  - Animal subject-detect tracking on Z8 / Z9
  - Tamron Di III lens compatibility additions
Approximate milestones — verify against the Techart firmware page for the authoritative changelog.
Megadap MTZ11
released 2023
Leica M lens → Nikon Z body
- 11 body-side contacts
- firmware updatable
- not weather sealed
- no glass — pass-through
- Motorised mechanical-AF adapter: a 4.5 mm voice-coil tube physically extends the rear flange to drive autofocus on M-mount rangefinder glass — the Nikon-Z counterpart to Techart's LM-EA9 for Sony.
- Works with any M-mount lens (Leica, Voigtländer Cosina, Zeiss ZM, 7Artisans, TT Artisan) — the lens itself doesn't need to know it's being autofocused.
- USB-C firmware updatable. Eye-AF tracking works on Z6 II / Z7 II / Z8 / Z9 with the latest firmware. AF speed is unhurried by design — best for static or low-motion subjects.
Firmware history
1. v1.02023
  - Initial release — motorised AF on M-mount glass for Z6 II / Z7 II / Z8 / Z9
2. v2.02023
  - Eye-AF subject tracking polish on Z8 / Z9 with the latest body firmware
  - Focus search speed and overshoot tuning
3. v2.12024
  - Zf compatibility
  - Closer minimum-focus calibration (more usable close-focus throw on 35mm / 50mm Summicrons)
Approximate milestones — verify against the Megadap firmware page for the authoritative changelog.
Novoflex NIKZ/NIK
released 2018
Nikon F lens → Nikon Z body
- no firmware updates
- not weather sealed
- no glass — pass-through
- CNC-German alternative to Nikon's FTZ / FTZ II for the manual-focus AI / AI-S Nikkor user — purely mechanical, no electronics, lighter than the FTZ, with Novoflex's dual-screw bayonet precision.
- No AF, no metering pass-through, no EXIF — every value (focal length, aperture, lens model) goes manual on the Z body. The tradeoff: precision mechanical tolerances and a lifetime warranty for daily use with classic manual-focus Nikkor glass (Noct-Nikkor 58 mm f/1.2, Nikkor 105 mm f/2.5 AI-S, Nikkor 28 mm f/2 AI, etc.).
7Artisans M-NZ
released 2020
Leica M lens → Nikon Z body
- no firmware updates
- not weather sealed
- no glass — pass-through
- Budget M-mount → Nikon Z mechanical adapter at sub-$30 — accessory to the 7Artisans M-mount lens line. Z body's 16 mm flange leaves the adapter as a substantial barrel to bridge to the 27.8 mm M flange.
- Looser bayonet tolerance than K&F Pro / Urth — adequate for casual use. For AF on M-mount glass to Nikon Z, the Megadap MTZ11 is the only working choice.
Megadap ETZ11
released 2021
Sony E (incl. FE) lens → Nikon Z body
- 11 body-side contacts
- firmware updatable
- not weather sealed
- no glass — pass-through
- 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.
- 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
1. 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
2. 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
3. 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
Approximate milestones — verify against the Megadap firmware page for the authoritative changelog.
Techart TZE-02
released 2023
Sony E (incl. FE) lens → Nikon Z body
- 11 body-side contacts
- firmware updatable
- not weather sealed
- no glass — pass-through
- Techart's successor to the TZE-01 — Sony FE / E → Nikon Z with autofocus, improved AF acquisition speed, and a broader lens-compatibility list than the first-generation TZE-01.
- Firmware-updatable; competes head-to-head with the Megadap ETZ21 Pro, usually at a slightly lower price. Native Sony G / GM glass is the most reliable; Sigma DG DN and Tamron Di III AF support is added over firmware revisions.
- Same 2 mm E → Z flange clearance — a thin ring; pair heavy telephotos with their own tripod collar rather than the adapter.
Firmware history
1. v1.02023
  - Initial release — Techart's second-generation Sony FE / E → Nikon Z autofocus adapter, succeeding the TZE-01
  - Phase-detect AF, Eye-AF, electronic aperture, EXIF and in-lens OSS pass-through on Z6 II / Z7 II / Z8 / Z9 with native Sony G / GM glass; faster AF acquisition and a broader maintained lens list than the TZE-01
2. v1.12024
  - Added support for Nikon Z bodies released since launch (e.g. Z f, Z6 III) as they shipped
  - Expanded the maintained third-party AF list (Sigma DG DN Art, Tamron Di III) and refined subject-detect tracking
3. v1.22025
  - Maintenance pass — additional third-party AF lens-compat entries and AF-reliability tuning to keep pace with the Megadap ETZ21 Pro firmware cadence

K&F Concept M42-NZ
released 2019
M42 (Pentax / Praktica screw mount) lens → Nikon Z body
- no firmware updates
- not weather sealed
- no glass — pass-through
- M42 (Pentax / Praktica 42 mm screw) lenses onto Nikon Z. Mechanical ring — no AF, no electronics. Most M42 lenses use an Auto/Manual switch (set to M) or a rear stop-down pin the flat adapter clears, so the aperture ring controls the diaphragm.
- M42's 45.46 mm register clears Nikon Z's 16 mm by 29.46 mm — the deepest mirrorless gap, so infinity is the most forgiving of any Z adapt. Fits Takumar, Helios, Industar, Jupiter and the rest of the vast M42 universe.
Fringer EF-NZ II
released 2023
Canon EF lens → Nikon Z body
- 11 body-side contacts
- firmware updatable
- weather sealed
- no glass — pass-through
- 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.
- No first-party EF → Z adapter exists — Nikon's FTZ / FTZ II are F-mount-to-Z only. A handful of lesser-known electronic EF → Z adapters exist with more variable reliability, but Fringer is the maintained, reputable choice.
- Best results on Sigma Global Vision EF (Art / Sports / Contemporary) and the Canon L USM zooms Fringer lists explicitly (24-70 f/2.8L II, 70-200 f/2.8L IS III, 100-400 L IS II). No screw-drive EF lenses exist — all EF AF runs through the in-lens motor, which the adapter drives electronically. The EF → Z ecosystem is younger and thinner than EF → Sony E, so check the current per-lens chart before buying.
Firmware history
1. v1.02023
  - EF-NZ II (FR-NZ2) launch — adds weather sealing and removes the tripod foot of the original EF-NZ (FR-NZ1) for vertical-grip clearance; AF, electronic aperture, IS and EXIF on Canon EF / EF-S and Sigma / Tamron EF-mount lenses across Z bodies
2. v2.302026
  - Current shipping firmware (2026-03) — periodic per-lens AF compatibility and newer Z-body support refinements; Fringer maintains an active compatibility chart

Common questions

Does the FTZ II adapter preserve autofocus on Nikon F lenses?: Yes for AF-S and AF-P lenses (motor lives in the lens) — full AF, VR, and electronic aperture all work on every Z body (Z9, Z8, Z7 II, Z6 III, Z5, Zf, Z50 II, Z30, Zfc). For AF-D and earlier screw-drive lenses, no — the FTZ II has no built-in screw-drive motor, so they become manual-focus with focus-confirm only. The original FTZ I and FTZ II differ only in tripod-foot construction; AF capability is identical.
What's Nikon's 58 mm f/0.95 Noct and why is it Z-mount only?: The Noct is a manual-focus, all-electronic 58 mm f/0.95 prime that exploits Nikon Z's unusually wide 55 mm throat and short 16 mm flange — geometrically impossible on Nikon F's 44 mm throat. Released in 2019, it's Nikon's flagship halo lens demonstrating the optical headroom Z's mount geometry allows; no AF, focus-by-wire only.
How does Nikon Z compare to Canon RF and Sony E for mount geometry?: Z's 55 mm throat is the widest of the three (RF 54 mm, E 46.1 mm) and its 16 mm flange is the shallowest (RF 20 mm, E 18 mm). The wider throat plus shorter flange gives Z the largest design envelope for fast, wide-aperture lenses — but the practical advantage is small for most photographers, and Z's third-party native lens count lags behind both RF and E in 2026.
