Last August, Megadap announced the ETZ11 autofocus adapter. This adapter allows photographers to use Sony E-mount lenses on full-frame APS-C and Nikon Z cameras. However, the adapter was plagued with compatibility and performance issues. Not even a year later Megadap is back with an all new second generation adapter, the ETZ21AF.

The new adapter has been completely reworked with new hardware and software. The software protocols have been rewritten using original Sony and Nikon protocol information, promising improved focusing speed and accuracy. In addition, the adapter promises better compatibility. You can use most E-mount lenses, including those from Sony, Tamron, Zeiss, Sigma, Voigtlander, and Samyang. You can also use manual lenses with or without chips.

If you’re using a lens with electronic contacts, EXIF ​​data will record most of the information, including focal length, aperture, shutter speed, and ISO, although lens brand information lens are not recorded. You can see the aperture on your camera and check it if the adapter lens has aperture coupling.

IBIS, optical image stabilization and all autofocus modes are supported, including real-time tracking, eye detection, subject detection and continuous autofocus. You can also use the in-camera focus stacking modes with a suitable lens. All AF-area modes, including single-point AF, are supported.

The ETZ21 is also improved when it comes to firmware. You can check the firmware version of the adapter in the camera itself or using a macOS or Windows computer. You can update firmware using an included USB update tool and plugging it into your computer.

The Megadap ETZ21 AF is constructed using a thin aluminum alloy and a stainless steel bayonet. The release button includes an improved design, and the plating on the adapter is more advanced. At 2mm, it’s a very thin adapter.

The Megadap ETZ21 is available to order now direct from Megadap for $249.
