Late last week, Sigma announced firmware updates for three lenses, including the 50mm F1.4 DG DN, the 105mm F2.8 DG DN Macro, and the 14-24mm F2.8 DG DN. Firmware updates for lenses don’t typically grab the headlines, but this particular update caught our attention for one notable reason: it enables these lenses to shoot at up to 120fps on the Sony a9 III.

Historically, Sony has limited third-party lenses to a maximum shooting speed of 15fps on its Alpha mirrorless cameras. So, a firmware update that allows for 120fps capture with third-party lenses is interesting.

However, it’s worth noting that the update comes with some limitations. First, 120fps shooting is not available when using continuous autofocus; it’s limited to AF-S and manual focus modes only. Second, this improved performance appears limited to the a9 III, as no other Sony bodies are mentioned in the release notes.

It’s unclear whether the lack of autofocus is due to a technical limitation or another restriction. DPReview has contacted Sigma and Sony for comment and will update this article if we receive additional information.

The new firmware updates are available now through Sigma’s firmware downloads page.
