What is sharpness?

Technically speaking, sharpness is defined as the acuity, or contrast, between the edges of an object in an image. A well-defined edge, one that makes an abrupt transition from one color or tone to another, thus giving definition to that object in the photo, is considered to be "sharp".

Does sharpness increase quality?

Sharpness is the most important contributor to image quality. In most cases, a picture that is not sharply focused on the subject is not considered a quality photograph. Even when using soft focus, the lens must be precisely focused on the subject to produce a quality image.
