Perhaps one of the most anticipated cameras to date was that of the a9 and although the initial release was not flawless, Sony has been earnestly working to resolve any unwarranted issues that may leave the user thinking this is anything other than the stellar camera it was intended to be.

Sony has released the newest firmware update 2.00 for the A9, and it is an important one, in a continuation of refining its flagship camera. This newest update addresses previous focusing issues with enhanced AF-C when tracking moving subjects as well as more stability when zooming.
