This difference in terms of refracting index affects the focus in your photos, and that’s when you get some of those annoying colourful halos along the edges.Ĭheck for colourful halos around the edges of subjects in your images. For example, blue wavelengths of light are able to pass faster through a lens compared to red wavelengths of light. However, it's impossible to find a lens without chromatic aberration, since it’s a physiological problem of all lenses when exposed to light.ĭispersion also has something to do with chromatic aberration: the refracting index (a number that tells you how fast the light is able to pass through a certain material) of the lens elements is different for various colours. In general, high quality, expensive lenses will logically minimise chromatic aberration better than basic lenses. See also: The Best Lenses for Wildlife PhotographyĪs you may have understood by reading the definition, chromatic aberration is an optical problem, so it all depends on the lens you are using.In this case, you can clearly see them along the edge of the mountain.Ĭhromatic aberration along the edge of the mountain. In simpler words, and as you can see from the photo below here (which is a roughly 100% crop of the original), chromatic aberration consists of some annoying colour halos that appear where they shouldn’t be. In reality though, different colours of light hit the lens at different speeds (and so, at different times), causing different types of chromatic aberrations to occur. Theoretically speaking, the perfect lens should be able to focus all the wavelengths of colours into one point, called “circle of least confusion”, where chromatic aberration is minimised. It’s quite a common problem in photography that affects almost all lenses, though high-quality lenses will present with less chromatic aberration compared to lower-quality ones.
