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. hasselbladhistorical.eu/pdf/lds/CB80.pdf hasselbladhistorical.eu/pdf/lds/CFE80.pdf Thank you in advance for your time.
