I did a lens comparison a while back between Leica R, Zeiss ZE Primes, Canon L series primes, and 60's/70's era Nikkor primes and there was no difference to my eye between any of them except for a slightly wider dynamic range with Leica. All other optical aspects like sharpness and color were visually identical. That's a pretty wide range in years and lens cost and I would suggest that even the top cinema prime is no more than maybe 5% better optically than any of these I tested.
