Certainly the lens lacks a little contrast, but nearly all of these older lenses do. Lens design and manufacture has improved over time as well as new lens coatings have been introduced. I don't find it a problem that they lack a little contrast, just add a little more during post processing. Some might find that remark a little disturbing, but then again I don't earn my living by being a professional photographer. They might see things a little different than myself.
