Nikkor DX kit lens group test 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.
Zoomed-out to 18mm with their apertures wide open, the most noticeable light fall-off comes from the DX 18-70mm. Almost 10% less dark in the corners are the DX 18-55mm and DX 18-135mm lenses, although the best result here comes from the DX 18-200mm; impressive considering it also has the longest focal range. |

Nikkor DX kit lens group test 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.
Zoomed-into their longest focal lengths and with their apertures wide open, the most obvious light fall-off once again comes from the DX 18-70mm, although the DX 18-135mm is right behind it; indeed the darkening in the corners of the 18-135mm is obvious even with the aperture closed to f8, see previous page.
Coming in way ahead of both these lenses are the DX 18-55mm and DX 18-200mm models which exhibit noticeably less darkening in the corners. Once again this is particularly impressive for the DX 18-200mm considering its large 11.1x focal range. |
