Pentax *istDL resolution comparison

  To measure resolving power we photographed the standard ISO 12233 test chart with each camera set to its best quality JPEG settings. We then set the bundled lenses to f8 using Aperture Priority mode. The crops are taken from the originals and presented here at 100%. Each number represents 100 lines per picture height (lpph), so a figure of 18 means a resolution of 1800 lpph.

The image left was taken with the Pentax *istDL using the 18-55mm DA at 35mm f8; the original JPEG measured 2.04MB. Resolving 1500 to 1550 lpph, the DL scores averagely for a 6 Megapixel D-SLR.
