Firmware Friday: Sigma fixes AF issue for MC-11 mount converter
posted Friday, July 21, 2017 at 3:56 PM EST
Our Firmware Friday roundup this week is going to be rather short and sweet, as we're only aware of two new updates for digital imaging devices. Sigma's closely-related MC-11 mount converters for Sony E-mount cameras have both received new firmware aimed at resolving autofocus issues with certain lenses.
If you want to know which lenses specifically, though, the answer is that we're not actually sure. Sigma's release notes for the new firmware -- which carry version number 1.06 for the Sigma SA to Sony E-mount variant, and version 1.08 for the Canon EF to Sony E-mount variant -- don't actually list the lenses involved.
What we can tell you, though, is that the affected lenses aren't officially supported by either mount converter in the first place. (Which we have to say makes it rather nice of Sigma to take the time to release an update just to fix an issue with unofficially-compatible lenses.) To find out if your own lenses now offer better AF compatibility, you can install the updates using Sigma's optionally-available USB dock accessory and its Sigma Optimization Pro software package.
And that's all for this week! Be sure to check back next time for more firmware news!
