[Updated Information] Operating conditions of the Nikon “Z7” and SIGMA’s interchangeable lenses for Nikon mount

Thank you for purchasing and using our products.

We would like to share results of our further investigations regarding the operating conditions of the Nikon “Z7” and SIGMA’s interchangeable lenses for Nikon mount.

When SIGMA’s interchangeable lenses in the current product lineup, listed below, are used in combination with the Nikon “Z7” and their “Mount Adapter FTZ”, both AF and AE operate without any issues.
Furthermore, lenses which incorporate Optical Stabilizer (OS) will work to maximum effect when both the lens’s OS and the in-camera stabilization are switched on simultaneously.
