Thank you for purchasing and using our products.
With the SIGMA 60-600mm F4.5-6.3 DG OS HSM | Sports and the SIGMA 70-200mm F2.8 DG OS HSM | Sports, we have found a phenomenon whereby when pressing the shutter button on the camera body, it may occasionally stop operating and not respond to the reoperation. In this circumstance, we would like to provide a lens firmware update free of charge to the customers using the applicable products with the serial numbers mentioned below.
We apologize for the inconvenience this may cause.
Phenomenon
Applicable products and Serial No.
Corresponding method
For customers using the applicable products with the mentioned serial numbers, we are going to provide a lens firmware update free of charge.
* The SIGMA USB DOCK cannot be used for this firmware update as it requires an adjustment to optimize each lens individually.
How to identify already supported products
Among the applicable products with the mentioned serial numbers, those that had their firmware updated have a black sticker on the lower right corner of the product gift box, as shown in the image below.

Thank you for purchasing and using our products.
We would like to share results of our investigations regarding the operating conditions of the Sony “a6400 (ILCE-6400),” released by Sony Corporation on February 22nd, 2019, and SIGMA’s interchangeable lenses for Sony E-mount.
With the SIGMA’s interchangeable lenses for Sony E-mount, both the AF and the AE work inter-connectedly, and they are compatible with the in-camera Lens Aberration Correction function:“Lens Correction” (“Peripheral illumination correction”, “Chromatic aberration of magnification correction”, “Distortion correction”). *SIGMA 19mm F2.8 DN | Art, SIGMA 19mm F2.8 EX DN, SIGMA 30mm F2.8 DN | Art, SIGMA 30mm F2.8 EX DN, and SIGMA 60mm F2.8 DN | Art are not compatible with the Fast Hybrid AF.
In addition, we found some phenomena particular to some products listed below. Regarding these phenomena, we are going to release a firmware update for improvement. The availability of the firmware will be announced on a later date.
Furthermore, the operating conditions of SIGMA’s SIGMA GLOVAL VISION (SGV) lenses via the MOUNT CONVERTER MC-11 are currently under investigation. After completing it, we are going to make an announcement.
Applicable products
Confirmed phenomenon
The stop position may vary when the shutter button is repeatedly half-pressed on the AF toward the same subject.
Applicable product
Confirmed phenomenon
With a6400 and cameras incorporating DMF mode, it automatically displays a magnified view as it gets in focus, when using the AF while the MF assist function is turned on.

Thank you for purchasing and using our products.
We would like to share the results of our further investigations regarding the operating conditions of the Canon "EOS R" and SIGMA’s interchangeable lenses for Canon mount.
When SIGMA’s interchangeable lenses in the current product lineup, listed below, are used in combination with the Canon "EOS R" and their "Mount Adapter EF-EOS R" or "Control Ring Mount Adapter EF-EOS R", both AF and AE operate without any issues. Furthermore, lenses which incorporate Optical Stabilizer (OS) will work with the OS function properly in effect.
In addition, 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 DG and DC lenses from Contemporary, Art and Sports line listed below which were released after March, 2018, or those of which firmware has been updated to Ver.2.0 or later. For other lenses, the Digital Lens Optimizer as well as the in-camera Lens Aberration Correction function cannot be used. Therefore, please set all to [OFF] before shooting.
Applicable products
DG Lens
DC Lens
* Camera’s "Scene Intelligent Auto mode" cannot be used.
Precautions for when DC lenses are used When SIGMA’s DC lenses where the image circle is designed to match APS-C sized sensors are used, "1.6x (Crop)" will not be set automatically. Please select "1.6x (Crop)" manually. There are future plans for a firmware update to be announced at a later date that will make the DC lenses from Contemporary and Art line compatible with the "1.6x (Crop)", to be set automatically, as well as Camera’s "Scene Intelligent Auto mode".
