No Ron, the digital sensor is ¼ the size of 45. To achieve optimal performance with the sensor you would need to shoot around f8. And that is what digital lenses are corrected for. On the other hand analog lenses are designed to perform optimally at 22. Using those lenses on a digital sensor at f8 you will not be at the optimal performance of the lens and at f22, with the digital back and an analog lens you will be in diffraction.
Additionally the digital lenses have higher resolution, check and compare MTF, less fall off, check the graphs, less distortion and better color correction, again, compare the graphs.
Then go look at what very large prints look like from a digital back and with digital lenses.
Yes digital lens is a bit misleading, they will outperform any medium format lens on film with a quality roll back! But there design purpose was superior results on digital backs on digital platforms, be that an Alpa or a Linhof M679 series body.
