Sometimes optical problems in a lens can create visible artifacts in your image. Lens aberration correction attacks two different kinds of optical problems. Vignetting is a darkening that can occur in the corners of your image. Vignettes most often occur with wide-angle lenses, and sometimes a vignette can add a nice effect to an image; it can bring attention to the center of the frame. Most of the time, though, you don't want vignettes in your image, and your camera has a feature to remove these when you're shooting JPEG images. Chromatic aberration occurs when the lens doesn't focus all wavelengths of light to precisely the same point. The practical upshot is that you'll see colored fringes around some areas of your image. As with vignetting, your camera can address these issues when you're shooting in JPEG mode. Lens aberration correction, which is in the first page of the shooting menu, is where you will find controls for both correcting vignettes and chromatic aberration. This…
