DxOMark review for the Nikon 24-120, the new constant f/4 aperture on DxOMark.Tuesday November 23 2010 Lens Review
Lateral chromatic aberration
Better construction enables the new zoom to perform a little bit better than the previous model when dealing with chromatic aberration. But there are still some perturbations, especially between 24 and 35mm at apertures ranging from f/4 to f/11. For the remaining zoom range, the aberrations are still noticeable between 35mm f/8 and 75mm f/5.6. The best performance of the 24-120mm f/4 is obtained between 50 to 120mm when stopping down above f/8.
Used on APS-C sensors, the scenario changes completely once again: the chromatic aberrations are noticeable along the whole zoom range between f/4 and f/5.6. Above f/8, the lens behaves quite well.
