As with distortion, lateral chromatic aberration can be corrected automatically in-camera and, in this case, can’t be disabled. Processing Raw files in our lab tests reveals uncorrected levels, which are generally worst towards the edges and corners of the image frame. Even so, the amount of colour fringing remains very low in almost all of the lenses. The only real exception is that uncorrected fringing can be quite noticeable towards the corners when shooting with the Yongnuo YN50mm f/1.8Z DF DSM at wide aperture settings, as revealed in this comparison graph.
