Resolution Chart Comparison (RAW)

On this page we're looking at Raw resolution for both the K-5 II and K-5 IIS. For a (more) level playing field we convert the files using Adobe Camera Raw. Because Adobe Camera Raw applies different levels of sharpening to different cameras we use the following workflow for these conversions:

  • Load RAW file into Adobe Camera RAW (Auto mode disabled)
  • Set Sharpness to 0 (all other settings default)
  • Open file to Photoshop
  • Apply an Unsharp mask tuned to the camera, in this case 100%, Radius 0.6, Threshold 0
  • Save as a TIFF (for cropping) and as a JPEG quality 11 for download

Both cameras used the 50mm F2.8 Macro lens at F5.6. We see slightly more resolution in the raw output from both cameras, with the K-5 II managing to resolve well up to around 2200LPH and the K-5 IIS just a little more, towards 2300LPH. Moiré quickly takes over as lines get closer together in the K-5 IIS, shown as slight coloration that appears well beyond the 2000LPH shown in this crop, an effect that is better controlled on the K-5 II.
