Hey Guys,

wonder if there are other Nikon Mount users who experienced this. It is not possible for my camera (newest FW) to communicate with the lens. I am not able to change aperture, which is pretty obstructive.

Is it just my Nikon mount?

Had some issues with the Sigma 24-70 Art, but was always able to control the aperture.

Any advise would be great!

Best regards.
