Resolution Chart Comparison
Comparison cameras:
- HP Photosmart R707 (5 mp, 3x zoom)
- Canon PowerShot S60 (5 mp, 4x zoom)
- Samsung Digimax V50 (5 mp, 3x zoom)
- Sony Cyber-Shot DSC-F88 (5 mp, 3x zoom)
Shots here are of the PIMA/ISO 12233 standard resolution
test chart (more of which are available in our comparison
database). This resolution chart allows us to measure the actual performance
of the lens and sensor system. It measures the ability of the camera to
resolve lines at gradually higher resolutions and enables us to provide
a definitive value for comparison purposes. Values on the chart are 1/100th
lines per picture height. Thus a value of 15 equates to 1500 lines per picture
height.
Studio light, cameras set to auto, all settings factory
default. If possible aperture was selected for optimum sharpness. Exposure compensation
+0.7 EV to +1.3 EV.

The R707 is certainly no slouch when it comes to resolving fine detail, and the images are pretty clean too. It is outperforming the Sony DSC-F88, and isn't far off the Canon S60 or Samsung V50 - two of the best 5MP compacts we've tested recently.
