Konica Minolta 5D 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 5D with the 18-70mm DT lens exhibits a little purple fringing at its widest position in line with its rivals. Fringing is virtually absent at the 70mm end, again in line with the competition. |

Konica Minolta 5D 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. The image left was taken with the Konica Minolta Dynax 5D and the 18-70mm DT lens at f8. Like other budget digital SLR lenses, the best macro performance was achieved using its longest focal length of 70mm. Here the lens captured an area measuring 82x54mm from a distance of 20.5cm. This result is around 20% lower than its rivals. |
