Resolution Chart Comparison (RAW)


For a (more) level playing field we also convert our resolution tests using Adobe Camera RAW. Because Adobe Camera RAW applies different levels of sharpening to different cameras (this confirmed) we had to use the following workflow for these conversions:

  • Set Sharpness to 0 (all other settings default)
  • Open file to Photoshop
Ricoh GXR/A12 50mm (3.9 MB, 12.3 MP) Leica X1 (4.3 MB; 12 MP)
Canon G11 (1.6 MB, 10MP) Panasonic GF1 (4.3 MB, 12.3 MP)

Despite of a reduction in perceived sharpness compared to the JPEG files the ACR conversion squeezes a small amount of additional measured resolution out of the Ricoh images. However, the increase is much smaller than on its peers. As we've mentioned in the RAW comparison of the studio shots other RAW converters (including ACR at default settings) can achieve better results on the GXR. See the RAW page of this review for details.
