What the Nerds Do / Using Neweer NW-ETZ to get focus confirmation and correct IBIS
« Last post by Snoogly on March 21, 2026, 21:47:01 »This seemed a rather nerdy thing to do, but it might be of interest to others. It enables me to get focus confirmation and correct IBIS info for any of my manual F mount lenses, and I just need to use my ancient iPhone to ‘edit’ the text file containing the connected lens’s data.
Connected NW-ETZ to my Mac and copied the lens text file to the Mac. Made several copies and edited them to match some of my Nikon F mount manual lenses. I don’t think you should rename the text file, so I placed each one in a lens-named folder. Then easy to copy a chosen text file to the adapter, opting to ‘replace’ the existing file. Works a treat, and the lens exhibits correct exit data on my ZF, I get the green light (and the traffic lights), and IBIS is correct.
So far it’s not exciting, as many have done this already. But I wanted to be able to do this on the fly without a Mac. So I connected a lightning ‘camera’ dongle to my iPhone 13 mini. This has a USB A socket and USB 3 for power input. I used my smallest USB power bank for power. Then I connected the Neweer USB cable and popped it on the adapter. On the iPhone I navigated to the set of folders where I had saved text files for my F mount lenses (files saved in my Dropbox). Selected a text file and then ‘shared’ to the ‘Files’ app and then on to the connected Neweer adapter. Again chose to ‘replace’ the existing file.
Bob’s yer uncle, it worked, and only took about three minutes. No need for any file editing out in the field, just dropped an existing text file on to the adapter.
I did this with Nikon F lenses, via an F to Sony adapter, but of course it would also work with other types of manual lenses with an appropriate adapter.
