cmos vs ccd is not the issue. the sensor is fine. its the adc thats old and needs to be changed to lower the read noise so it is not overpowering the midtone shadows. the only way to fix this is for dpreview and other review sites to make a new test so it becomes clear to novices that it is important. then canon will fix it pronto. we should thank the fed meranda review for bring this to light. the way is is shown is confusing and misleading. needs to be more technical test.
