Olympus E-400 wide-angle uniformity comparison
 |
|
To measure and compare the Olympus E-400's
kit lens vignetting and light fall-off we photographed a white target with a
highly diffused custom filter using it and a number of rival models.
Here are the results for each camera with their kit lenses set to their
widest focal lengths with the apertures wide open and the focus set to infinity.
The images were analysed with Imatest and the full areas presented here
at a reduced resolution. Bigger percentages are better.

14-42mm at 14mm f3.5
Mean corner fall-off: 63.6% |
| |
| The image above was taken with the Olympus E-400 using the Zuiko Digital 14-42mm kit lens zoomed-out to 14mm with its aperture wide open. Here the light falls off in the corners to an average of 63.6% of the center
measurement. This is roughly similar to the Canon and Panasonic kit lenses, although all are beaten by the Zuiko Digital 14-45mm in this particular test. |

Olympus E-400 telephoto uniformity comparison
 |
|
To measure and compare the Olympus E-400's
kit lens vignetting and light fall-off we photographed a white target with a
highly diffused custom filter using it and a number of rival models.
Here are the results for each camera with their kit lenses set to their
longest focal lengths with the apertures wide open and the focus set to
infinity.
The images were analysed with Imatest and the full areas presented here
at a reduced resolution. Bigger percentages are better. |
14-42mm at 42mm f5.6
Mean corner fall-off: 85.7% |
| |
The image above was taken with the Olympus E-400 using the Zuiko Digital 14-42mm kit lens zoomed-in to 42mm with its aperture wide open. Here the light falls off in the corners to an average of 85.7% of the center
measurement, which again is similar to the Canon kit lens, although measurably superior to both the Zuiko Digital 14-45mm and Leica 14-50mm. |
