Here are the results as calculated with Thomas Fors' ACR Calibrator v3.7 using Adobe Photoshop CS2 and ACR3.3. So far only 3 Nikon and 4 Sigma lenses were used, but many more are scheduled for inclusion. Except for Sigma 17-70 all the lenses follow certain calibration pattern, so average figures could be calculated and used with success. Even that lens can be used with averaged values, but with somewhat lowered total saturation.
