Just a heads-up that the Neewer Sony E to Nikon z adapter, in conjunction with an E to F adapter, enables the focus confirmation square with unchipped manual lenses. It’s crazy, but it works … I know because I bought one.
However, … The camera cannot ‘see’ beyond the Neewer adapter, which always reports itself as being a 50mm lens. Also, IBIS is disabled.
The result is focus confirmation with any manual lens, at the expense of no IBIS and wrong exif information.
I contacted Newer support, and got a rather unclear response… When connected to a computer with the provided USB cable a text file can be found, which contains the reference to 50mm. They mentioned this file, but did not explain if it can be self-changed, or how to do it. Even if possible, it would mean connecting the adapater to a computer every time you use a different focal length manual lens.
A couple of other people on forums and YouTube comments are also in contact with Neewer, trying to figure out if the issues can be resolved.
It really does give focus confirmation, however unlikely it sounds, but I cannot live with the caveats, and don’t want to fart around trying to fix it - so I will be sending it back today.
