Megadap has announced its newest lens adapter. It’s the Megadap EFTZ21 (buy here). It allows you to use Canon EF mount lenses on your Nikon Z mirrorless cameras. It’s a full-frame adapter but also works with APS-C.
The company says that it offers full autofocus support with electronic aperture synchronisation. It also supports IBIS in conjunction with IS in the lenses. And, of course, you get full communication for EXIF data.
Megadap – Changing Mounts
Megadap is typically known for its Sony E to Nikon Z adapters. I mean, they’ve released three of them. The first was the Megadap ETZ-11, which came in 2021. It was followed up in 2022 by the Megadap ETZ-21 and by the Megadap ETZ-21 Pro last year (buy here).
It looks like the company’s all Sony’d out a little bit for now, though. They’re switching things up. The new Megadap EFTZ21 is a Canon EF to Nikon Z adapter. It allows you to use Canon EF mount lenses on your Nikon Z bodies. And you can do so with full autofocus, stabilisation and EXIF data.

It’s a full-frame adapter, but it will also work with Nikon DX bodies. This adds around 150 Canon EF mount lenses to the potential lineup for Nikon Z shooters. So, it opens up a lot more options. Considering how cheap used EF lenses are now, they’re viable options, too.
You know, it’s funny, when the Canon 5D Mark II was released, people jumped on video and they were usually trying to adapt Nikon lenses to Canon bodies. Now, thanks to Megadap, it’s the other way around.

Megadap EFTZ21 Features
According to Megadap, the EFTZ21 focuses on performance and convenience. It incorporates a range of features to help make your photography experience go more smoothly.
- Auto-Focus Support: Achieve smooth and precise focusing for every shot.
- Automatic Aperture Synchronization: Quickly adjust aperture settings from
both the camera body and lens. - Support IBIS Function: Support either camera IBIS or lens IBIS.
- EXIF Signal Transmission: Record essential lens and shooting data directly on
the camera body. - Firmware Upgrade in Camera: Update firmware without the need for
external tools. - Compatibility with Canon EF Lens Library: Access an extensive range of
automatic lenses from the Canon EF mount. - Custom Control Ring: Personalize settings like aperture, exposure
compensation, and ISO sensitivity. - Customizable L-FN Button: Improve efficiency with customizable functions
such as focus lock and exposure lock. - Full Button Function Support: Utilize all lens functions, including focus
distance button, IBIS button, and AF/MF switching button. - Three-Proof Design: The adapter features dustproof, waterproof, and anti-
slip capabilities, making it versatile for any shooting conditions. - Premium Build: Constructed with pure copper bayonet mounts and premium
finishes for durability. - Anti-Vignetting Opening Design: Ensures unobstructed light entry, tailored
to the camera’s CMOS photosensitive area.

The firmware for the adapter can be updated in-camera from Nikon Z bodies, and it features customisable function buttons and control rings, allowing fingertip access to various camera functions while shooting.
The company says it’s dustproof, waterproof (yes, “waterproof”, not just weatherproof) and anti-slip for use in a variety of weather conditions.
