M-Z 6bit adapter ring

The adapter does not fit right with the Leica Elmarit 2,8/28 mm, so I'm very disappointed about this waisted a 100 USD for the adapter.
The lens hood is not in the right position, so there are dark corners in the final pigs.

I would like the return the adapter but I'm not aware how to do it.

A very much useful tool for adapting vintage lenses. Just having the green box focus confirmation in my Nikon Zf is a game changer!

It didn’t do what it’s supposed to do. Didn’t recognize all my 2 m-mount lenses (M-Summicron 50/2 and VM Voigtlander 75/1.8 Heliar Classic). I even bought a kit to 6-bit coded them! The maximum apertures and focal lengths are mis-identified, the green box focus confirmations are working though. Could you have this replaced?

Perfect adapter to my Nikon ZF with autofocus confirmation

I love using this to adapt my M mount lenses to my Zf. It should really be clarified that this adapter cannot show aperture data stopped down below f5.6. Getting accurate metadata was a major reason to buy this. I also wish the rotator dial had more common focal lengths, or that the method for choosing focal length were more versatile. Still, it lets great focus features work and opens us up to lenses that actually suit manual shooting, so I’ll live with the quirks
