Next year we are going to get a new A9III and A7IV camera for sure. The new Sony A7rV is more likely to be introduced in 2022. I know Sony read us so please give them a general idea of the necessary improvements (Note: I didn’t add features like fully articulating screen, same A7sIII EVF…because these are kind of obvious to be featured on the A7rV too).
If you have any more suggestions please comment this post!
