Olympus E-400 corner sharpness comparison
|
 |
|
To measure and compare the Olympus E-400's corner sharpness we photographed the Enhanced Digital Camera
Resolution Chart with it and a number of rival models, each using their
best quality JPEG and default image tone and sharpening settings.
We used the kit lenses at their widest and longest focal lengths and
with various apertures.
The crops are taken from
the extreme lower left corner of the chart and presented here at 100%. |
Zoomed-out to wide angle with the aperture fully opened, the Zuiko Digital 14-42mm exhibits a little softening and light fall-off in the extreme corners, but it's no worse than other typical kit lenses, and indeed performs slightly better than the Zuiko Digital 14-45mm lens here.
Zoomed-in to telephoto, the Zuiko Digital 14-42mm
is again slightly soft with the aperture wide open, but again it's comparable to the other kit lenses on test. Overall, it's a good result considering the new lens is significantly smaller and lighter than the E-500's 14-45mm kit lens.
Note: crop details which appear smaller here are
due to them being captured with lower resolution cameras and / or a lens
which couldn't focus as close to the chart. In each case though, the crop
still represents the extreme left corner of each camera's frame. The Canon 400D / XTi shows a different part of the chart because it takes wider 3:2 aspect images, but these still represent the extreme left corner. |
