To be fair, the optical light gathering ability of a full frame f/1.4 lens is slightly better than that of the Hasselblad 80mm f/2.8, and modern digital sensors have eclipsed 6x6 film in every respect, such as resolution, sensitivity, and indeed even dynamic range. Photo technology has in fact progressed a fair bit in the last half a century.

Of course, nothing can touch the light gathering ability of that Zeiss 50mm f/0.7, but then that lens wasn't very sharp anyway and modern digital sensors can go up to way higher ISO than possible with film while still making decent pictures.
