Sigma has released compatibility notes for its interchangeable lenses when used with the Canon EOS R and Mount Adapter EF-EOS R, as well as updated compatibility information related to the Nikon Z7. The updates follow Sigma's compatibility note for the Nikon Z7 released in late September, during which time the company said it would continue testing products and publishing future updates.

According to the company, its interchangeable lenses for Canon mount "do not have any issues with general operation" when used with the Canon EOS R and EF-EOS R adapter. However, users will need to disable the in-camera Digital Lens Optimizer feature before using a Sigma interchangeable lens with the model.

Sigma states:

When the Digital Lens Optimizer is switched [OFF], but “Peripheral illumination correction”, “Chromatic aberration correction” and “Distortion correction”, located within the in-camera Lens Aberration Correction function is switched [ON], the appropriate corrections can be achieved in accordance with the optical characteristics of each lens. This is applicable to lenses listed below which were released after March, 2018, or those of which firmware has been updated to Ver.2.0 or later.

In regards to its updated Nikon Z7 compatibility data, Sigma has released a list of 36 interchangeable lenses for Nikon mount that it tested and found compatible with the Nikon Z7 and Mount Adapter FTZ. When used together, "both AF and AE operate without any issue," the company stated in its latest release.

The full list of compatible lenses is available in the press release below:

[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.

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.

24-35mm F2 DG HSM | Art

[Phenomenon]- It may occasionally stop recording while shooting video. It is planned to be resolved by a firmware update.

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. It is planned to be resolved by a firmware update.

85mm F1.4 DG HSM | Art

[Phenomenon] - It may occasionally show overexposure when narrowing down the aperture from F5.6 while shooting. It is planned to be resolved by a firmware update.

APO 800mm F5.6 EX DG HSM

[Phenomenon] - Please focus using MF, since it is difficult to achieve sufficient focusing accuracy. 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.

[CANON COMPATIBILITY NOTE]

Thank you for purchasing and using our products.

We would like to announce that, as of this moment SIGMA’s interchangeable lenses for Canon mount in the current lineup do not have any issues with general operation when they are used on the “EOS R”, released by Canon Inc., via their “Mount Adapter EF-EOS R”.

In addition, please note the information below when using our lenses.

1. With SIGMA’s interchangeable lenses, the Digital Lens Optimizer located within the in-camera Lens Aberration Correction function cannot be used. Therefore, please set the Digital Lens Optimizer to [OFF] before shooting.

When the Digital Lens Optimizer is switched [OFF], but “Peripheral illumination correction”, “Chromatic aberration correction” and “Distortion correction”, located within the in-camera Lens Aberration Correction function is switched [ON], the appropriate corrections can be achieved in accordance with the optical characteristics of each lens. This is applicable to lenses listed below which were released after March, 2018, or those of which firmware has been updated to Ver.2.0 or later.
