Konica Minolta 5D wide-angle uniformity comparison
 |
To measure lens vignetting and light
fall-off we photographed a white target with a highly diffused custom filter.
Here are the results for the bundled lenses at their widest focal lengths
with the apertures wide open in Aperture Priority mode. The images were
analysed with Imatest and the full areas presented here at a reduced resolution. The image left was taken with the Konica Minolta Dynax 5D and the 18-70mm DT at 18mm f3.5. The light falls off to an average of 73.5% in the corners, which while not quite up to the Nikon results, remains better than the Canon and Pentax models. |

Konica Minolta 5D telephoto uniformity comparison
 |
To measure lens vignetting and light
fall-off we photographed a white target with a highly diffused custom filter.
Here are the results for the bundled lenses at their longest focal lengths
with the apertures wide open in Aperture Priority mode. The images were
analysed with Imatest and the full areas presented here at a reduced resolution. The image left was taken with the Konica Minolta Dynax 5D and the 18-70mm DT at 70mm f5.6. The light falls off to an average of 90.1% in the corners, which is similar to the Nikon and comfortably above the Canon and Pentax results. |
