Just received the Fringer EF-NZ adapter for my Voigtlander 125/2.5 in Canon EF mount and can report that everything works perfectly
With electronic adapters it’s always the questions wether they also support third party lenses, so far its fifty fifty. On the Sony a7RII the Commlite adapter worked great with the Canon 100-400 but got the aperture wrong for the CV125 whereas the Metabones worked flawlesly with both.
Similar with the Techart Pro Sony FE to Z adapter, the Sony Zeiss 35/1.4 works great but the aperture is off by one click for the Voigtlander 15/4.5 FE and the CV125 with the Metabones adapter. When the latter reports f/2.5 the aperture isn’t fully opened yet, one turn extra on the dial does open it entirely but now the aperture reads f/2.4 on both the topscreen of the Z6 and the exif.
The electronic aperture control on the Fringer adapter works flawlesly though and there’s zero play in the mount, it also comes with a removable Arca foot which works great to balance the CV125 on a tripod. At €299 its my most expensive adapter yet but its well worth it when the CV125 works like a native lens, it also enables future workarounds for some of my unchipped lenses knowing it works with third party chips but more on that later.
Attached pics of the CV125 on the Z6, the exif wideopen with the Fringer adapter and finally the exif with the Techart Pro & Metabones stack. Please note that besides the proper aperture registration it also turns the AF Mode into MF mode where other adapters kept the Z6 incorrectly in AF-C mode.
