I plan to begin shooting portarits of people at "wide-open" apertures using analog film.
I want to choose between the Hasselblad 80mm CFE or 80mm Cb lens.
I am aware that the Hasselblad 80mm 2.8 CB lens is a simplified/cheaper version of the Hasselblad 80mm 2.8 CFE lens.
I took the time to look at the MTF charts for both the 80mm CFE and 80mm Cb lenses.
I was surprised to find, that, the cheaper 80mm Cb lens actually produces better and more uniform results across the frame, wide-open at f/2.8.
And, although at f/5.6 the 80mm CB suffers a little in the center, it again seems to do a better job across the frame and out to the edges, actually becoming sharper.
Is this correct?
Did i misunderstand the MTF charts?
Below are the two MTF charts I viewed for comparison.

Thank you in advance for your time.
