Sony releases firmware V2.10 for a7 III and a7R III

  By Kaitlyn Kerr

Sony has released a new firmware update for the a7 Mark III and a7R III cameras.

With the previous update, v2.0 a couple months ago, there were occasional issues with saving data on both camera models, as well as an issue where the cameras would sometimes not recognize third party memory cards. Sony pulled the update, but has now released the replacement, v2.10, which addresses these issues and removes any concern.

All features of the previous (v2.0) version are updated, including improved optical stabilization, support for the 400mm f2.8 and 24mm f1.4 GM lenses, and support for use with the LA-EA3 adapter, including the support of all focus areas.

Firmware links are below.
