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.
I think it had a 7x7cm film - that's a humongous, 49cm^2 sensor compared to a regular full-frame camera, which clocks in at 8.64cm^2. As far as I can tell, the iPhone's is a tiny 0.25cm^2.
Combine with no-holds-barred lenses and you're bound to get fantastic pictures even six decades ago.
