All of the updates are available from Sigma's website, and the links are provided below.

Sigma f/1.4 30mm DC DN | Contemporary for Micro Four Thirds mount

Firmware update v1.2 addresses an issue when the lens was mounted to the Olympus OM-D E-M1 Mark II in which the autofocus did not work when C-AF was selected.

Sigma SD Quattro H body

This firmware update, v1.01, adds no new features or functions but fixes several issues:

Images weren’t recorded if Low and RAW were selected.

Quick Preview wasn’t always displayed in the electronic viewfinder.

Certain indicactors didn’t display when the setting was changed when shooting in Custom Modes C1-C3.

The SD Quattro H would lock up when shooting in tethered mode via Sigma Capture Pro software.

Sigma Photo Pro 6.5

Sigma is offering some suggestions to those who use the software and attempt to enable “GPU Acceleration Mode,” which either won’t activate or causes the software to crash.

Sigma explains that GPU acceleration can’t be activated if the system has less than 1GB of VRAM.

Sigma also recommends that the user ensure that the video driver is updated to the latest version.

Separately, Sigma has updated the software to v.6.5.1, which will now open RAW files from Sigma Quattro cameras, even if the computer’s video driver hasn’t been updated.
