Older lenses in particular can display this flaw, called spherical aberration, which makes it impossible to render the image of a flat surface that lies parallel to the focal plane in sharp focus across its entirety. When the image center is sharp, the edges won’t be; conversely, when the edges are sharp, the center will be soft. Stopping down the lens usually lessens the aberration. Curvature of field is especially important to photographers shooting flat objects such as paintings, prints, currency, or documents. Macro lenses designed for shooting these types of subjects are referred to as flat-field lenses, and are typically free of curvature of field even at their widest apertures. | |
