Pentax *istDL macro comparison
 |
To measure macro performance we photographed a custom chart using the bundled lenses at a distance and focal length which delivered the maximum possible reproduction. The dark lines are 10mm apart. The image left was taken with the Pentax *istDL and the 18-55mm DA lens at f8. Like other budget digital SLR lenses, the best macro performance was achieved using its longest focal length of 55mm. Here the lens captured an area measuring 66x44mm from a distance of 12cm. This is essentially the same as the competition, although superior to Konica Minolta. |
