With the announcement of the new Sony a9 II any rumors circulating that it would include a new 36MP processor have been quickly extinguished.
Sony has decided to stick with the existing 24.2-megapixel 35 mm full-frame stacked CMOS sensor from the a9.
So for Alpha Shooters hoping for more megapixels you may now be wondering how the Sony a7R IV compares with the a9 II.
In this article I’m going to take quick look at the key differences in specifications between these two range topping cameras.
