On our optical bench, the lens turned in better-than-average SQF performance, showing sharpness and contrast in the Excellent range at the three tested focal lengths. (Lenses in its zoom and price categories usually drop to Very Good at the long end.) In DxO Analyzer 2.0 testing, we found Imperceptible barrel distortion at 40mm (0.08%), and Slight pincushion distortion at 100mm and 150mm (0.16% and 0.15% respectively) -- a surprisingly good showing for a kit lens, especially at 40mm. Light falloff was gone from the corners by f/5 at 40mm and 100mm, and by f/5.6 at 150mm -- about average. The lens' magnifying power leaves something to be desired, with maximum magnification ratios at the constant close-focusing distance of approximately 55 inches ranging from 1:28.5 at 40mm to 1:7.6 at 150mm. By comparison, the longer Nikon digital-only kit zoom (55-200mm, $170, street) gets to a tight 1:3.4 at its outer focal length.
