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.

<Phenomena particular to 4 lenses were confirmed after our announcement of September 28th>
After careful investigation, we confirmed some phenomena particular to 4 products listed below.
Regarding a firmware update for the SIGMA 24-35mm F2 DG HSM | Art, 50mm F1.4 DG HSM | Art and 85mm F1.4 DG HSM | Art, we are going to announce them at a later date.

■SIGMA 24-35mm F2 DG HSM | Art
[Phenomenon]
It may occasionally stop recording while shooting video.
[Future Course of Action]
It is planned to be resolved by a firmware update.

■SIGMA 50mm F1.4 DG HSM | Art  
[Phenomenon]
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.
[Future Course of Action]
It is planned to be resolved by a firmware update.

■SIGMA 85mm F1.4 DG HSM | Art
[Phenomenon]
It may occasionally show overexposure when narrowing down the aperture from F5.6 while shooting.
[Future Course of Action]
It is planned to be resolved by a firmware update.

■SIGMA APO 800mm F5.6 EX DG HSM
[Phenomenon]
Please focus using MF, since it is difficult to achieve sufficient focusing accuracy.
[Future Course of Action]
There is no plan for a firmware update.


When the lenses listed below are used, due to product specifications, the in-camera stabilization cannot be turned off. In addition, the Auto Power Off function cannot be used. Please manually turn the power [OFF] after shooting.

・Discontinued products have different operating conditions depending on each product and their shipping period. For details, please contact your nearest authorized SIGMA subsidiary / distributor.

Various lenses shipped from SIGMA before November, 2013
We have previously confirmed that some phenomena such as AF not working correctly with some lenses released or shipped from SIGMA before November, 2013, when they are used on Nikon’s digital SLR cameras incorporating the latest firmware. Under this circumstance, we will update the lens firmware free of charge. If the products do not operate on a Z7, even when they are listed above, the lens firmware update may improve the situation.

For customers who have these applicable products, please contact your nearest authorized SIGMA subsidiary / distributor for further details.

*1 For products of which firmware was updated after November, 2013, a firmware update is not necessary.
*2 It is not possible to update the firmware of products for which our support period has finished.
*3 For products with an engraved edition number of A012, C013 or S013, the lens firmware can be updated using the optional SIGMA USB DOCK.
