When it comes to the chromatic aberration, once again the Tamron compares favourably with the Nikkor. At 18 mm both lenses show the aberration at a medium level of 0.10-0.11%. The 50-100 focal lengths are to the Tamron’s advantage, with the results at the level of 0.04% so two times lower than in the case of the Nikkor – although it’s worth noticing that neither the level of 0.04% not that of 0.08% will be especially bothersome in out photos. At 200 mm both lenses fare similarly once again, having the results near 0.11%. The highest aberration level of the Tamron we see at the maximum focal length where it reaches 0.15% - really high. We can’t compare that performance with the Nikkor, though, as its focal range ends at 200 mm. In the stabilized megazooms’ class the Sigma 18-200 OS fares the worst, with the aberration at all focal lengths ranging from 0.10% to 0.14%.
