Assertion: camera's aperture | /r/HasAspect | lower sharpness
Facets:
value: due to diffraction
type: CAUSE

text: By contrast, the minimum aperture does not depend on the focal length – it is limited by how narrowly the aperture closes, not the lens design – and is instead generally chosen based on practicality: very small apertures have lower sharpness due to diffraction, while the added depth of field is not generally useful, and thus there is generally little benefit in using such apertures.
