Nikkor 18-200mm corner sharpness, tested with Nikon D2X

  To measure corner sharpness we photographed the Enhanced Digital Camera Resolution Chart with each lens using a Nikon D2X in Aperture Priority mode. The D2X was set to Large Fine JPEG mode, optimised for quality rather than size, and with A for Image Sharpening and Tone Compensation.

Each lens was tested at its widest and longest focal lengths and with various apertures using Aperture Priority mode. The crops are taken from the lower left corner of the chart and presented here at 100%. The 18mm crops show a larger area of the chart because minimum focusing distances forced us to shoot it from further away.

At the 18mm wide angle end, the Nikkor lens delivers clearly superior corner sharpness than its cheaper rivals, although to be fair, the Sigma and Tamron lenses improved considerably just a short distance in from the extremes. The story is also the same at the 200mm telephoto end, with the Nikkor comfortably out-performing the competition.
