Canon patent a new viewfinder for professional DSLRs that features magnification ratio of 0.82X. Let me know you that the 5D Mark IV viewfinder features magnification ratio of 0.71X and the Canon 1DX Mark II features magnification ratio of 0.76X.
As we all know that viewfinder is the most important user interface of the DSLR camera. Now let’s know what is magnification ratio in DSLR camera ?. It generally refers to how big the viewfinder image appears, for example a theoretically perfect viewfinder will have 1X magnification ratio.
1X is the size of things appear when you look them with your eye. Now if your Camera, say Canon 1DX Mark II have 0.76X magnification ratio makes things appear to be approx three-quarters the size they look to be with your naked eye. And to be clear 0.82X is better than 0.76X.
Here is the patent details
