Nikkor DX 55-200mm f/4-5.6 VR shortest focal length uniformity comparison
|
 |
DX 55-200mm VR at 55mm f4
Mean corner fall-off: 66.1% |
|
To measure and compare the Nikkor 55-200mm VR's vignetting and light fall-off we photographed a white target with a
highly diffused custom filter using it and a number of rival lenses.
The lenses were tested at their
widest focal lengths with the aperture wide open in
Aperture Priority mode.
The images were analysed with Imatest and the full
areas presented here at a reduced resolution. Bigger percentages are better. |
| The image above was taken with the Nikkor DX 55-200mm VR at 55mm f4.
Here the light falls off in the corners to an average of 66.1% of the centre
measurement, which results in much more noticeable darkening in the corners compared to the 70-300mm VR when it's zoomed out to 70mm - although to be fair the latter is corrected for a full-frame body. The scores for the DX 18-135mm and DX 18-200mm VR are also included here for completeness, but can't be fairly compared to the two telephoto zooms due to their much wider short focal lengths. The more relevant comparison is below when all four are zoomed-in. |

| The image above was taken with the Nikkor DX 55-200mm VR at 200mm f5.6.
Here the light falls off in the corners to an average of 60.1% of the centre
measurement, which is roughly similar to the DX 18-135mm when it's zoomed-in, but not as good as the DX 18-200mm VR at 200mm. The 70-300mm VR once again delivers the best result here, although again it should do being designed for a full-frame body. That's enough for our studio tests, so let's check out some real-life results in our DX 55-200mm VR Gallery. |
