Nikkor DX 18-55mm VR wide-angle uniformity comparison
|
To measure and compare light fall-off at wide angle, we photographed a white target using a
highly diffused custom filter with each lens at its
shortest focal length and the aperture wide open.
The images were then analysed with Imatest and the full
areas presented here at a reduced resolution. Bigger percentages are better.
With the Nikkor DX 18-55mm VR zoomed-out to 18mm and its aperture wide open, the light falls-off in the corners to an average of 48.3% of the centre measurement. This is slightly worse than its predecessor, although you wouldn't notice any real different in practice - interestingly the test does show the light falling off more sharply on the older Mark II model, making its darkening arguably more conspicuous. |

Nikkor DX 18-55mm VR telephoto uniformity comparison
To measure and compare light fall-off at telephoto, we photographed a white target using a
highly diffused custom filter with each lens at its
longest focal length and the aperture wide open.
The images were then analysed with Imatest and the full
areas presented here at a reduced resolution. Bigger percentages are better.
With the Nikkor DX 18-55mm VR zoomed-into 55mm and its aperture wide open, the light falls-off in the corners to an average of 63.9% of the centre measurement. Again this is a worse than its predecessor, but with a gradual fall-off, it's nothing you'd really worry about in real-life shots. |
