“Vignetting” is a drop in brightness at the edges of a photograph. Vignette control reduces vignetting for type E and G lenses (0 Identifying CPU and Type G, E, and D Lenses). Its effects vary from lens to lens and are most noticeable at maximum aperture. Choose from High, Normal, Low, and Off.
Depending on the scene, shooting conditions, and type of lens, JPEG images may exhibit noise (fog) or variations in peripheral brightness, while preset Picture Controls that have been modified from default settings may not produce the desired effect. Take test shots and view the results in the monitor. Vignette control does not apply to movies (0 Recording and Viewing Movies) or to pictures taken with lenses that support FX format.
