Compared to the Sony DSC-F707

The next two pages are dedicated to the comparison of the DSC-F717 to the model it replaces, the DSC-F707. This comparison has been added primarily at the request of the many DSC-F707 owners on our Sony Talk Forum and also to note any distinct improvements in image quality between the two cameras, however minor.

The first quite interesting difference is that the F717 appears to be 0.7 EV (three quarters of a stop) more sensitive than the F707. That is that it exposed the shot at 1/1250 sec where as the F707 used a shutter speed of 1/800 sec, resulting image brightness was the same. It's also fairly clear that the F717's colour balance is 'different' compared to the F707, blues seem to have shifted more towards a pure blue (less green influence) and greens are toned down slightly. Otherwise noise levels and resolution are virtually identical.
