Sony Cyber-shot DSC-R1 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 cameras
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%. Like most lenses, purple fringing is visible at wide angle with the R1's aperture open, although the Carl Zeiss optics keep it under check as you close the aperture or zoom-in. It's a big improvement over the earlier F828. |

Sony Cyber-shot DSC-R1 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 Sony DSC-R1 from 25cm using its lens at 71.5mm f8 (120mm equivalent). Here the camera captured an area of 102x68mm which is the least impressive of the group, although in its favour, there's little to no distortion. |
