Digital Camera Info has published a full review of the Olympus E-520.
There’s one of the best Live View modes on the market (with auto focus), a good image stabilization system that’s built into the body, comprehensive presets and a high degree of customizability and control. However, the test results for noise levels, white balance and dynamic range were so poor that they dragged down an otherwise good camera.
