Sigma just released an updated Z7 compatibility study, which thankfully is mostly just “everything works as it should”, though there four exceptions, and one which is pertinent to me:
50mm F1.4 DG HSM | Art: When starting to shoot with the subject completely out of focus, the response to the AF operation is intermittent. It is necessary to release several times or to turn the focus ring once to release. It is planned to be resolved by a firmware update.
I have seen what might be that issue, but I’ve also seen the same symptoms with the kit 24-70/4, and Nikon’s own F-mount lenses, so, I’m curious what the distinction is between the Nikon Z7’s general autofocus issue of this nature, and this specific issue that’s supposedly only applicable to the Sigma 50/1.4 Art.
