The configuration of that lens is similar to a Tessar (1+1+2) so it can be very well corrected, the maximum aperture is reasonably small, and you are using only a very small area from the center of the image circle so it ought to be sharp - modern lenses added just coating for higher contrast, faster apertures, wider usable FOV and (sometimes) a smaller size. Bellows mounting an old lens like this gives you a very flexible tool if you can live with the lower contrast and the somewhat higher tendency to flare - and contrast can often be quite dramatically improved with judicious use of USM after RAW conversion. These old lenses are good enough for most photography - real photography, that is
