Chromatic aberration is an optical defect that causes light rays of different wavelengths to focus at different points along the optical axis of the lens. It is manifested as band of one color at frame transitions around contrasting edges in the photo. There are two types of chromatic aberration: longitudinal and lateral. Lateral chromatic aberration is the color fringing that occurs because the magnification of the image differs with wavelength. It tends to be far more visible than longitudinal. The aim of this research is to examine the influence of focal length on the appearance of lateral chromatic aberration. For the purposes of the experiment, we used one mirrorless camera (Sony Alpha A1), while the lenses were variable. We used Sony 24-70mm f2.8 GM and Tamron 70-180 f2.8 to check how the focal length affects its appearance.
