Operating conditions of the Sony “α6400 (ILCE-6400)” and SIGMA’s interchangeable lenses for Sony E-mount

Thank you for purchasing and using our products.

We would like to share results of our investigations regarding the operating conditions of the Sony “α6400 (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.

[Confirmed phenomenon]
The stop position may vary when the shutter button is repeatedly half-pressed on the AF toward the same subject.

[Confirmed phenomenon]
With α6400 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.
