To measure and compare the corner sharpness of the Nikkor DX 55-200mm VR, we photographed the Enhanced Digital Camera Resolution Chart with it and a number of rival lenses at their shortest and longest focal lengths using a D80 at various aperture settings. The D80 was set to Aperture Priority, Large Fine JPEG mode and the Optimise
Image parameter set to Normal.
The crops are taken from the lower left corner of the chart and presented here at 100%. The crops which show a slightly larger area of the chart are due to minimum focusing distances forcing us to shoot from a little further away. No crops have been resized. |
