Olympus E-500 purple fringing comparison
 |
To measure purple fringing caused
by lens chromatic aberrations and sensor blooming, we photographed a custom
test chart, left, with areas of very high contrast. We used the bundled
lenses at their widest and longest focal lengths with the aperture wide
open in Aperture Priority mode. The crops are taken from the upper left
corner of the chart and presented here at 100%. The E-500 with 14-45mm lens exhibits a little purple fringing at its widest position in line with its rivals. Fringing is virtually eliminated at the telephoto end, again like most of the competition.. |

Olympus E-500 macro comparison
 |
To measure macro performance we photographed a custom chart using the
bundled lenses at a distance and focal length which delivered the maximum
possible reproduction. The dark lines are 10mm apart and the result is
not cropped. Smaller areas are preferred in this test. |
