With BOLD I marked the features that are appealing to me and I can get real improvement of my workflow… or I just simply want to have. Although we have already seen many of these features in the recently released A7RIV, they were not presenting in the previous A9, so they have to be mentioned here. The lack of Anti-flickering detection for example was one of the reasons I wanted to skip the first generation of A9. 


I am going to follow up with another article about the most important features for me of the new A9II. But let’s see what I miss or need to see updated in the A9III (this list may be upgraded in the future and moved to our WISH LIST page).

What do I want to see in v.III

  • Newer sensor – Sony has already patented 30Mpx stacked BSI sensor, which could be a good replacement of the current 24Mpx one.
  • Improved Menu system
  • Lit buttons
  • Adding 4k 60p video

What do you like to see in the future A9III or in a firmware update for the A9II?
