Megadap ETZ21 PRO+ Autofocus Lens Adapter for Nikon Z - FE Lens

In this review the Megadap ETZ21 PRO+ is evaluated as an adapter that lets photographers mount Sony FE lenses on Nikon Z bodies while retaining critical automation. The bottom line: it is aimed at hybrid shooters who already own FE mount glass and want reliable autofocus, aperture control and stabilization on Z series cameras. The reviewer found the adapter preserves lens functions such as AF modes and image stabilization, and that its thin 2mm plane keeps flange distance accurate so optical performance remains intact.

Key Features

• Broad compatibility: Works with a wide range of FE mount lenses from Sony, Tamron, Sigma, Zeiss, Voigtlander and others so users can reuse existing glass.
• Native-like autofocus: Uses an original protocol equivalent conversion mode that enables AF-S, AF-C and AFF video autofocus on compatible camera bodies.
• Electronic aperture support: Automatic synchronized aperture reporting to the camera means F stops are recognized and exposure control works from the camera body.
• Stabilization enabled: Lens optical stabilization functions normally through the adapter for lenses with built-in IS and for camera bodies that handle IBIS.
• Thin adapter profile: The adapter ring has a 2mm plane thickness to maintain correct flange distance and avoid mechanical vignetting.
• Field-upgradeable firmware: Firmware can be updated via the camera memory card to improve compatibility and add fixes over time.

Who It's For

The ETZ21 PRO+ is best for Nikon Z shooters who own or plan to borrow FE series lenses and want reliable autofocus and aperture communication rather than a purely manual adapter. It is also useful for videographers who need AFF or time-lapse features preserved when using FE glass on a Z body.

Photographers who only need occasional manual-adapter use, or who require guaranteed compatibility with every legacy lens model, may prefer a native mount lens or an adapter with a specific cross-brand compatibility guarantee. Street photographers who demand the utmost in minimal bulk might also prioritize smaller, lighter options.

Pros & Cons

Pros

• Enables autofocus and AF modes (AF-S/AF-C/AFF) for many FE lenses on Nikon Z bodies.
• Retains image stabilization and reports aperture values so exposure and F stops are recognized.
• Thin 2mm plane maintains proper flange distance and reduces risk of vignetting.
• Firmware updatable for ongoing compatibility improvements.

Cons

• Compatibility varies by lens model; some third-party lenses may require firmware updates or may not support every function.

Our Verdict

The Megadap ETZ21 PRO+ is a practical, value-oriented adapter for Nikon Z users who want to make full use of Sony FE lenses with autofocus and aperture control.
