I have recently bought this piece of shit adapter to use on my z5, but I came across some issues which. I'm unsure whether my unit is not working properly or if it's intentional. I'd love to hear from someone using it regularly. Keep in mind that I do not own any 6-bit coded lenses.

I cannot set the proper focal length for any of my M-Hexanons (28, 50, 35 & 90). Other lenses/LTM-M adapters work fine. It defaults to some lenses with wrong focal lengths and max apertures and no way to change that. As I don't need the 6-bit reader, and it's recessed, I just taped over it with electrical tape. This solves the issue, and lets me choose the correct focal length using the dial.

They advertise that aperture data can be saved to the EXIF if I set the correct aperture value in camera (meaning the same as I set the lens to). The issue is, that the camera only lets me set values between f/0.95 and f/5.6. Is it supposed to work like that? That seems like such an arbitrary value. Therefore, both the max aperture and the set aperture are wrong in the EXIF. With a "dumb" adapter, I at least can set the max aperture of the lens and that gets saved correctly.

I love the front/back focus indicator and focus trapping, but I'm quite disappointed by the inability to set the correct aperture value, or at least only the correct max aperture instead of having 2 wrong values in the EXIF. Is mine just faulty, or can anyone confirm those issues?
