Resolution Chart Comparison
Comparison cameras:
- Sony Cyber-Shot DSC-F88 (5 mp, 3x zoom)
- Nikon Coolpix 5200 (5 mp, 3x zoom)
- HP Photosmart R707 (5 mp, 3x zoom)
- Samsung Digimax V50 (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.

From a detail point of view the DSC-F88 is best described as 'fair to middling', though the images are nice and clean, with very little in the way of moire or sharpening artifacts, meaning they respond well to software sharpening. We would perhaps have expected more from a camera that boasts a Carl Zeiss Vario Tessar lens, but given the design compromises inevitably arising from the ultra-compact 'folded' optics, these results are actually well within acceptable boundaries.
