The Sony a6400 looks like it has very good AF, but even without a firmware update, the Sony a9 does better in my opinion. There are some videos showing off Sony’s new AF system on the a9, but I wonder how fast the Sony a9II will be. We now know that the Sony a9 sensor far surpasses the current a9’s capabilities and the a9’s full potential probably won’t be unlocked until the follow-up Sony a9II, but it is great that Sony is providing a very Fujifilm like firmware update that is providing a lot of extra functionality. Many have wanted to see Sony release updates like this and they finally have, so let us hope they continue updating cameras like this far into the future because it will keep them competitive with Canon/Nikon entering the mirrorless market.
