Lens resolution doesn't necessarily translate to maximum image sharpness in particular shooting scenarios, digital or otherwise. For instance, when subjects are not neatly aligned near a narrow plane orthogonal to the lens axis, employing a bit of lens tilt may enable shooting at a considerably larger aperture without losing focus on any of the subjects. In such cases, as a result of diffraction effects at larger apertures, a tilt/shift (or view camera) lens that fares comparatively poorly in resolution tests may nevertheless produce a sharper image of the subjects than a lens without movements could ever hope to produce, even in theory. Yet many feel tilt/shift effects are overused and passé, and mistakenly believe they are always achievable in post…
