Sharpness is a subjective quality attribute of an image or a lens. Sharpness indicates the visually perceived quality of details of an image or details reproduced by a lens. It is associated with both resolution and contrast of reproduced details (within an image or by a lens).The DxOMark score for Sharpness is based on the Perceptual Megapixel (P-Mpix) concept that weights the Modulation Transfer Function (MTF) of the lens with the human visual acuity.

An image’s degree of clarity in terms of focus and contrast.
Visual sensation of the abruptness of an edge. Clarity.
A term used to describethe ability of a lens to render fine detail clearly; dependent on the contrast andresolution of a lens and varies with the f/stop; in general, a lens is sharpest atthe middle apertures. Also technically can be explained as clarity of the photographicimage in terms of focus and contrast. Largely subjective but can be measured to someextent by assessing adjacency effects, i.e. the abruptness of the change in densitybetween adjoining areas of different tone value.
