English term or phrase: sharpness
Definition from MIR Web Development Team:
A term used to describe the ability of a lens to render fine detail clearly; dependent on the contrast and resolution of a lens and varies with the f/stop; in general, a lens is sharpest at the middle apertures. Also technically can be explained as clarity of the photographic image in terms of focus and contrast. Largely subjective but can be measured to some extent by assessing adjacency effects, i.e. the abruptness of the change in density between adjoining areas of different tone value.

Example sentence(s):
  • This kit is destined for travel, as it takes you from 20mm to 300mm without a lot of weight or bulk, provides flexibility with the zooms, sharpness with the fixed focals, low-light capabilities with the 85mm. bythom.com
  • A lot of photographers don't realize that hand holding a camera (even if it or the lens has image stabilization), isn't the way to get the maximum possible sharpness. Bob Atkins
  • Sharpness tests are unlike real photos because a test does everything possible to eliminate any source of unsharpness. In a lab, nothing moves and the target is usually flat. kenrockwell.com
