Faster isn’t always better

Like most photographers…I am not immune to the siren’s song of very fast lenses. And even less immune to the lure of lenses that are fast and designed to deliver performance at maximum aperture – think of the Zeiss Otus series, for instance. We’re even willing to compromise with older designs that perhaps don’t perform or resolve quite to the level we’ve come to expect from modern lenses on modern high resolution sensors, but write it off as being ‘characterful’ or ‘nostalgic’. Or even trying to rationalise that we don’t need such high resolution since most of the frame is out of focus anyway, plus we want a smooth transition between the bits that are and the bits that aren’t. And then we try to adapt lenses to systems they were never designed for (here, and here) – with varying degrees of success. However: the reality is we probably don’t need such tools the vast majority of the time, and even from a creative standpoint – a wider aperture doesn’t necessarily make an image better.
