Lenses render differently in various ways, unless someone wants to make an argument that all lenses since the beginning produce the exact same results. How one will receive these differences, assuming they’re even noticeable or relevant outside of a direct A/B comparison, will of course depend on the individual.
And as noted above, how these characteristic notably manifest will often depend on the type of photo taken. I have a 1934 lens that, due to flare (a technical fault), actually creates, for me, a desirable ‘glow’ around certain elements. However, this effect is not always present, as one might guess.
So while the article’s facetious statement has its points, it is equally foolish for one to buy the most modern and expensive lenses, employing the latest technologies, while simultaneously dismissing the fact that older lens (largely as a consequence of technological evolution) perform differently. And the benefits (if any) of these differences are subject to subjective interpretation.
As I’ve stated before, my favorite period in photography roughly stems from the 1930s to the 1960s, and not because of the lenses used. But this said, those lenses used were, nevertheless, more than sufficient for the applications that mattered to me.
