Viltrox EF-Z Reviews

Second Viltrox I've had to exchange

By Steve
Rated 1 out of 5
Date: 2025-12-11

Feels well built, but the electronics would not link up with the Nikon ZR. The ZR wouldn't recognize the adapter, the lens, or allow for aperture changes. Auto-focus did not work either, but the biggest issue was that when the adapter was on, the camera won't fire/record. I could get the ZR to roll without a lens, but soon as I connected the mount, the shutter button stops functioning. Tried to plug it into my computer to update the firmware and it wouldn't mount so ended up exchanging it for the Fringer brand and that worked right away.

Useless with Z6 II, Z7 II and Z9

The latest firmware for this adapter was released more than a year ago and it is not compatible with any of the newer models / firmware versions. Older camera firmware had some issues controlling the lens aperture but on the newer version the lenses are not even recognized.

See any errors on this page?

Will this adapter work with Cannon EF 28-135mm ...

Will this adapter work with Cannon EF 28-135mm f/3.5-5.6 IS USM Standard Zoom Lens? It's not included in the Viltrox website, not sure if can work on my old cannon lens. Thanks!
Asked by: Anonymous
Yes, the adaptor will be electronically compatible with some exceptions such as autofocus. The focus confirmation will be available as well as aperture, metering reading and manual focus assist methods depending on which Nikon Z camera you will be connecting with your old Canon EF 28-135mm via Viltrox EF-Z Lens Mount Adapter for Canon EF or EF-S-Mount Lens to Nikon Z-Mount Camera.

2nd customer review says Viltrox EF-Z works ...

2nd customer review says Viltrox EF-Z works "flawlessly" with Cannon MP-E and Nikon Z mount camera, but that lens doesn't work with my Nikon Z 7 which registers F-- error. (Lens clearly correctly attached. Wonder about firmware.) - ?
Asked by: Richard
Richard, thanks for the answer above. Could you advise as to how to install the firmware. When I attach the adaptor to Mac all I see is menus in Chinese. I am asked to find a pfu file on the hard disk. Thanks in advance.
