With the in-camera processing taken out of the equation, the E520 looks pretty good against its predecessor. The E510 retains its advantage in terms of sharpness but doesn't handle highlights nearly so well as the 520. The E520 has retained much more detail in the paperclips, rendering them much more convincingly than the older model, which clips the highlights rather aggressively.
