Colour fringing in telephoto lenses is generally most apparent as lateral chromatic aberration, which tends to show up around highcontrast edges towards the edges and corners of the image frame. A typical example is dark leaves and branches or the edges of buildings against a bright sky. Current and recent Nikon cameras correct for this automatically but, when disabled for lab tests, control over colour fringing is relatively poor for both Nikon AF-S DX 70-300mm lenses on test, especially towards the long end of the zoom range.
